UI: move "use_select_nearest_on_first_click" into it's own panel

Add a new panel called "Tweaks" so we can get feedback from users
about minor tweaks to behavior as exposing these minor changes.

Currently this only has a single item in it, however we may want to
get feedback from users about small changes in the future so I'd
prefer to have a place to list these kinds of options.
