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.

Un-implement Deref for Table (#546)
Remove `Deref` implementation for `Table`, to make sure we're using
`Table` and not `BTreeMap`.

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`.

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 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.

Add env_var(key) and env_var_or_default(key, default) functions (#280)
`env_var(key)` looks up the value of the environment variable with name `key`, aborting execution if it is not found.

`env_var_or_default(key, default)` looks up the value of the environment variable with name `key`, returning `default` if it is not found.
