Updated skills and more

This update a few usability tweaks and lots of fixes and improvements to skill descriptions. Many skills now show more information about exactly they affect your characters.

Step by step I'm fixing all the little gaps and unfinished features, and I'll try and keep up this steadier pace of updates. I have a long back log of issues to address and am trying to focus on broken or missing features before I move on to balance and polish chagnes.
