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.

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

Refactor run::run and Config (#490)
Improve color parsing, add `ConfigError`, put `invocation_directory` on Config object, return error code from `run::run` instead of exiting.

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.

e8c25423b8 Display alias with --show NAME if one exists
Given the following justfile:

    alias b := build
    build:
        echo 'Building!'

Just will show the alias along with the recipe:

    $ just --show b
    alias b := build
    build:
        echo 'Building!'
