 - Bash,JIT: Fixed Bash shell integration

0.1.5

* Added

- In zsh, for the grammar `--color=(always|never)` and input `--color=<TAB>`, you will now see `always` and
  `never`, not `--color=always` and `--color=never`.   This generalized to all subword completions of course.
- Descriptions can now contain escaped characters, e.g. a quote character or a backslash.
- More readable parsing errors using the chic Rust crate
- Scraper is now based on a bunch of regexes instead of a complicated parser.  This simplifies the code a lot.

* Changed

- If multiple literals have the same decription, they're now grouped into a single line (this can be
  controlled with `zstyle ':completion:*' list-grouped true/false`)

* Removed

- Single brackets external commands as they're superfluous (replaced with triple brackets ones)
