Crash when switching between characters

[emil-nasso]

If i open up vitality expand the character list and then switch over to the skill planner and start swiching characters rapidly, a few times, the application crashes. Will attach debug information.

It does this reliably for me. Every time.

I'm reasonably certain that this was (partially) fixed in release v0.3.2b (https://github.com/sixones/vitality/releases/tag/v0.3.2b). I stopped it from crashing, but didn't fix the underlying problem.

While looking it over I put in another small fix so that when switching between characters the skills for whichever plan under the new character is selected are properly shown. Vitality should really be keeping track of which plan/skill is currently selected for each character and reselect them when switching, but that's a larger task.
