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.
