uiuiui - fixed a bug which let running applications crash if switched style

from phase to any other. Reason was that in phase-style a special menubaritem-
drawroutine was set but not RESET to qte default if this style was removed
I'd implemented the unPolish routine and just set this callback to 0 (qt-default)
and now it works nice.
