Tweaked and rearranged a few options
Fix the skill wheel's mouse handling to be better

Redundant code was redundant
Tweaked a few things in the Respec script, fixed a few things in test scripts

Changed and redid a portion of the Stim checking code
Merge remote-tracking branch 'remotes/origin/master' into menurewrite
