Changelog:

- Added `getGroupByName() getGroupByGid() getUserByName getUserByUid()` methods to the `Bash` class.

- Fixed a bug inside the `localStorage` caching logic that saved only 32 characters out of 36 in the signature UUID.

- Added support for reverse order sorting in the quick sort implementation.
