Changes to llviewermenu.cpp are better viewed without space changes
^Put together both RLVa Embedded and RLVa Main menus while building Advanced menu, labeling them RLVa; once the advanced menu is built and added to MenuBar, rlvMenuToggleVisible() is called.
Added onChangedMenuLevel() to rlvcommon.cpp
Added rlvMenuToggleVisible(), tweaked to only perform necessary operations for now, other parts left commented out for future use.
Removed menu visibility handling from RlvHandler::setEnabled()
NOTE: RLVa has only been updated in pertinent areas, from what I can tell we are a bit behind in other places, too.
-Nametag bubble visbility is oddly inconsistent. May vanish with future planned UI merges...
-VBOs are PAINFULLY slow on ATI hardware. This repos self-compiled davep/shining-fixes branch, so I'll leave the ball in LL's court for now regarding that.
Most the changes are due to InventoryObjectList* changing to LLInventoryObject::object_list_t*, LLInventoryItem::II_FLAGS* changing to LLInventoryItemFlags::II_FLAGS* and also const'ing.
Certain perms for certain asset types(callcard&landmarks) have been laxed, as per LL's V2.
LLInventoryType now does lookups mostly though new lldictionary class.
LLLandmark using boost for callbacks, instead of custom class structure.
