Viewmode fixes: - Now need to press shift+F3 to set additional viewmodes. Just pressing F3 will only toggle between standard 1st and 3rd person. - SpectatePlayer should now return the correct currentViewMode during both spectate and demo playback. Removed hack for getting the viewmode - Can now switch between all viewmodes during demo playback - Fix SpectatorMode.Update not being called in third person during demo playback
