Subject: EXT-7485 FIXED Provided update of 'save as' button status and save
 outfit panel status. 1 published LLCOFObserver as LLOutfitObserver(moved from
 llpaneloutfitedit.cpp to lloutfitobserver.h) 2 decoupled outfit edit panel
 and observer by replacing pointer to panel with signals and made observer as
 singleton 3 moved call of LLAppearanceMgr::getInstance()->updateIsDirty()
 from outfit edit panel to observer(discussed with IB) 4 modified updating of
 combo button state on outfit panel using LLOutfitObserver 5 modified refresh
 of outfit name and status on outfit change event using LLOutfitObserver 6
 removed unnecessary LLWatchForOutfitRenameObserver that caused excessive
 updates of outfit panel status name
