Add the --choose subcommand (#680)
The `--choose` subcommand runs a chooser to select a recipe to run. The
chooser should read lines containing recipe names from standard input,
and write one of those names to standard output.

The chooser defaults to `fzf`, a popular fuzzy finder, but can be
overridden by setting $JUST_CHOOSER or passing `--chooser <CHOOSER>`.

Add option to print recipes in source order (#669)
Add an `--unsorted` flag, which makes `--list` and `--summary` print
their entries in source order.

Trim completions and ensure final newline (#609)
Trim whitespace at beginning and end of generated completions.
Additionally, since some editors will automatically insert a final
newline into text files, make sure a final newline is present.

Reform indentation handling (#565)
Improve indentation handling in preparation for implementing inline
submodules. This changes the lexer to only parse freeform text inside
the first indent after a ':', so that just can be extended with new
indented constructs which are not recipe bodies. In addition, the lexer
should now handle multiple levels of indentation correctly.

Resolve functions (#550)
Modifies parsing to return strongly-typed `Thunk`s, which contain both
the function implementation, as well as the correct number of arguments.

This moves unknown function and function argument count mismatch errors
to parse time.

Resolve alias targets (#548)
During analysis, resolve alias targets from `Name`s to `Rc<Recipe>`,
giving us type-level assurance that alias resolution was performed, and
avoiding the need to look up alias targets in a separate table when
running.

Resolve recipe dependencies (#547)
Make analysis resolve recipe dependencies from names (`Name`) to recipes
(`Rc<Recipe>`), to give type-level certainty that resolution was performed
correctly and remove the need to look up dependencies on run.

Avoid fs::canonicalize (#539)
Previously, we used `fs::canonicalize` to ensure paths used in search
were absolute. This lead to bad behavior when the justfile was symbolic
link to a file in another directory. Additionally, on Windows, this
produced paths in extended length syntax, which, I believe, has
compatibility issues.

This diff replaces uses of `fs::canonicalize`  with a simpler algorithm
that roots path in the invocation directory (which will be a no-op if
said path is already absolute), uses `Path::components` to remove extra
`/` and `.`, and resolves instances of `..` without following symlinks, by
removing the `..` and the component that proceeds it.

Refactor Compilation error to contain a Token (#535)
Use a `Token` to represent the error context, instead of a mess of
fields. Remove write_message_context in favor of `Token::write_context`.

Add shell setting (#525)
Add a `set SETTING := VALUE` construct.

This construct is intended to be extended as needed with new settings,
but for now we're starting with `set shell := [COMMAND, ARG1, ...]`,
which allows setting the shell to use for recipe and backtick execution
in a justfile.

One of the primary reasons for adding this feature is to have a better
story on windows, where users are forced to scrounge up an `sh` binary
if they want to use `just`. This should allow them to use cmd.exe or
powershell in their justfiles, making just optionally dependency-free.

Reform positional argument parsing (#523)
This diff makes positional argument parsing much cleaner, along with
adding a bunch of tests. Just's positional argument parsing is rather,
complex, so hopefully this reform allows it to both be correct and stay
correct.

User-visible changes:

- `just ..` is now accepted, with the same effect as `just ../`

- `just .` is also accepted, with the same effect as `just`

- It is now an error to pass arguments or overrides to subcommands
  that do not accept them, namely `--dump`, `--edit`, `--list`,
  `--show`, and `--summary`. It is also an error to pass arguments to
  `--evaluate`, although `--evaluate` does of course still accept
  overrides.

  (This is a breaking change, but hopefully worth it, as it will allow us
  to add arguments to subcommands which did not previously take
  them, if we so desire.)

- Subcommands which do not accept arguments may now accept a
  single search-directory argument, so `just --list ../` and
  `just --dump foo/` are now accepted, with the former starting the
  search for the justfile to list in the parent directory, and the latter
  starting the search for the justfile to dump in `foo`.

Gargantuan refactor (#522)
- Instead of changing the current directory with `env::set_current_dir`
  to be implicitly inherited by subprocesses, we now use
  `Command::current_dir` to set it explicitly. This feels much better,
  since we aren't dependent on the implicit state of the process's
  current directory.

- Subcommand execution is much improved.

- Added a ton of tests for config parsing, config execution, working
  dir, and search dir.

- Error messages are improved. Many more will be colored.

- The Config is now onwed, instead of borrowing from the arguments and
  the `clap::ArgMatches` object. This is a huge ergonomic improvement,
  especially in tests, and I don't think anyone will notice.

- `--edit` now uses `$VISUAL`, `$EDITOR`, or `vim`, in that order,
  matching git, which I think is what most people will expect.

- Added a cute `tmptree!{}` macro, for creating temporary directories
  populated with directories and files for tests.

- Admitted that grammer is LL(k) and I don't know what `k` is.

Move subcommand execution into Subcommand (#514)
Moves the code which executes subcommands into Subcommand:run,
delegating to separate functions for each subcommand. This reduces the
disgustingness of `run::run` a bit, and paves the way for future
refactoring and cleanup.

Reform Parser (#509)
Just's first parser performed both parsing, i.e the transformation of a
token stream according to the language grammar, and a number of consistency
checks and analysis passes.

This made parsing and analysis quite complex, so this diff introduces a
new, much cleaner `Parser`, and moves existing analysis into a dedicated
`Analyzer`.

Use constants instead of literals in arg parser (#504)
- Differentiate between `arg`s, which are flags and options, and `cmd`s,
  which are mutually exclusive subcommands

- Replace string literals, like "EVALUATE", with constants, like
  `cmd::EVALUATE`, since they're slightly less error prone.

- Remove `Config::evaluate`, and handle it like other subcommands

Start pulling argument parsing out of run::run() (#483)
run::run() is pretty unwieldy. As a first step in improving it, this
commit pulls most of the argument parsing into the `config` module.

It also renames `Configuration` to `Config`, just to be easier to type.

Add context to deprecation warnings (#473)
Previously, warnings upon encountering a deprecated use `=` in
assignments, exports, and aliases would print a message without any
indication of where the offending `=` was. This diff adds a proper
`Warning` enum, and uses it to report context, as is done with
compilation and runtime errors.

Use pub(crate) instead of pub (#471)
Eventually, there will probably be a `crate` visibility specifier that
does the same thing as `pub(crate)`. This commit replaces `pub` with
`pub(crate)`, so when `crate` is available we can easily switch to it.

Remove dependency on brev (#462)
Just's dependency on brev was the cause of a
fairly deep branch of the transitive dependency
tree. To decrease build time and make the life of
packagers easier, this diff moves the functionality
that Just was using in Brev into Just itself, and
removes the dependency on Brev.

Fortunately, the only functionality that Just was
using was the output function and OutputError
enum, so this was easily done.
