Hooks for the "nearby media" UI.

Added LLViewerMediaImpl::set/getDisabled(), which will prevent a media instance from loading.

Added LLViewerMedia::set/getInWorldMediaDisabled(), which will disable all inworld media fom loading.

Added LLViewerMedia::getPriorityList() and made the priority comparitor public.
