Updated Trad Chinese for Qt interface.

Based on https://github.com/hrydgard/ppsspp/pull/749
Initial implementation of vf2h.

Fixes Fat Princess and possibly other stuff.
Correct prefix handling in vf2h/vh2f.
Make changing register values actually work.
Allow changing fpu/vfpu regs.
Fix bIgnoreBadMemAccess ignored in GetPointer.
Keep track of whether we're in the runloop or not.
Wait for the runloop to end in savestates/debug.

This way, even if the runloop hasn't checked coreState yet, we will wait.
Add a timeout so quit doesn't hang.

Kinda like before except now it'll quit faster if possible.
