SingularityViewer/indra/llui/llmenugl.cpp
Lirusaito 3739639295 Merge branch 'Moap' of git://github.com/Shyotl/SingularityViewer into VoiceUpdate 
Conflicts:
	indra/newview/llfloateractivespeakers.h - llparticipantlist.h got changed from a panel to a layoutpanel
	indra/newview/lloverlaybar.cpp - Silly conflict, I change one line, Shyotl changes the next two.

Compile fixies:
	indra/newview/llavataractions.cpp needed to include llnotifications.h
	indra/newview/llvoicechannel.cpp needed to include llnotifications.h
