Default Avatars button option added to Toolbar prefs.
Adds debug setting ToolbarVisibleAvatar
Hooks into "avatar_picker_url" login response on opensim.
Also includes hooking up of DestinationGuideShown to startup, which was left unstaged from the initial commit of the Destination Guide.
Adds llfloaterdestinations.* and floater_destinations.xml (needs translations, but not really)
Adds GenericErrorPageURL, DestinationGuideURL (not persistent), DestinationGuideShown, and DestinationGuideRect to debug settings
Removes ShowcaseURLDefault in favor of DestinationGuideURL from upstream.
Also Adds ToolbarVisibleDestinations for the toolbar button, but I'll need to set up a nice way to make the button invisible when the url is empty before adding it to the gui... maybe.. or maybe it's just not important.
This commit comes with support for dynamically changing destination guide page based on opensimextras simulator features cap
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
Things still probably can be culled to shorten this file, but what definitely wasn't needed is removed.
People who want to learn keyboard shortcuts now need only hover their mouse over the buttons on the toolbar.
