Steps to reproduce:
1) Load Pathfinder Advanced from basic
2) File new
3) Go to skills, -5 to everything, true because of all scores set to 0
4) Roll scores, all at 10
5) Go to skills, still -5 to everything in the HTML pane
6) Toggle any skill -> rerender and A-ok
Quick-fix: rerender the skills pane in the background if ability scores are changed.
Quick-fix2: rerender the skills pane when you switch to it from another pane.
This also happens when equipping magic items that alter skill bonuses or ability scores.
Also made the skills edit table respond to changes in ability scores.
