Adding a Settings menu to the bar with two options:

• Mark Mode - Right click photos to mark them with one of several icons for later tagging/moderating passes.

Full Changelog: v2.2.2...v2.4.0

v2.2.2 - Second Tagged Release :)

This is a single-purpose release - changes the update URL to point to the latest release, instead of latest main version of the code. That way I can test stuff out and it won't break people's setup.

v2.2.1 - First Tagged Release

Just sent this out to some people, so time to create proper releases.
