/editors/featherpad: Update to 0.14.0

Changelog picked from https://github.com/tsujan/FeatherPad/releases:

V0.14.0

This release is mostly about speeding up syntax highlighting, especially for
big documents. In some cases (e.g., with HTML, XML, CSS, Bash or Perl),
the job is done multiple times faster.

Also:
- A bug is fixed in handling relative file paths that contain no slash.
- JavaScript template literals (back quotes) are supported.
- CSS syntax highlighting is fixed and improved.
- Small fixes.
