Class detection and zone crashes

[tknarr]

The fix I tried for manual class redetection after a zone crash didn't work. I'll be making some more tries at it to see if I can get it to work. The problem is I can't really test it except when a zone crashes on me, so debugging and checking changes takes time. The problem seems to be tied to coming back in without exiting the program (so the UI isn't reinitialized) but with no change in class name (so the OnChange that normally handles class detection doesn't trigger) leaving the class-name property uninitialized.

The current workaround is to camp back in to a character of a different class, then camp to the original character.
