Add subsequent dependencies (#820)
Subsequents are dependencies which run after a recipe instead of prior.
Subsequents to a recipe only run if the recipe succeeds. Subsequents
will run even if a matching invocation already ran as a prior
dependencies.

Reform and improve string literals (#793)
- Combine and simplify string and backtick lexing.
- Allow newlines in strings and backticks.
- Add triple-delimited indented strings and backticks. Common indented literal non-blank line leading whitespace is stripped.
- If a literal newline is escaped, it will be suppressed.
- Backticks starting with `#!` are reserved for a future upgrade.

Unify string lexing (#790)
Unify lexing of backticks, cooked strings, and raw strings. Also allow
newlines in backticks and cooked strings, since I can't think of a reason
not to.

environment variable.

Add conditional expressions (#714)
Add conditional expressions of the form:

   foo := if lhs == rhs { then } else { otherwise }

`lhs`, `rhs`, `then`, and `otherwise` are all arbitrary expressions, and
can recursively include other conditionals. Conditionals short-circuit,
so the branch not taken isn't evaluated.

It is also possible to test for inequality with `==`.

Add variadic parameters that accept zero or more arguments (#645)
Add "star" variadic parameters that accept zero or more arguments,
distinguished with a `*` in front of the parameter name.

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 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 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.
