mask modifier properly works in weightpaint and edit modes now. note that modifiers should not have to provide a applyModifierEM function, there's really no reason to not pull the result from applyModifier if applyModifierEM doesn't exist, it's not like we don't have a dozen *EM functions that do just that, anyway. fixes 22192. {merged 28543 into trunk}
