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.

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 `==`.

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`.

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`.

Refactor lexer tests (#498)
- Refactor the lexer tests to be more readable, abandoning the
  previous string-based summary DSL in favor of a more obvious
  sequence of `TokenKinds` with optional lexemes. The new tests
  also test that token lexemes are correct.

- Move duplicated `unindent` function into a shared crate,
  `test-utilities`. This new versionless dev-dependency will
  prevent publishing to crates.io, at least until rust-lang/cargo/pull/7333
  makes it into stable. If we publish a new version before then,
  test-utilities will need to be published to crates.io, so we can depend
  on it by version.

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.
