CHUI-337 FIXED: To avoid confusion with a classes "...conversation..." and in accordance with the naming convention in the project, some classes and corresponding files should be renamed:

LLIMConversation -> LLFloaterIMSessionTab LLIMFloater -> LLFloaterIMSession LLNearbyChat -> LLFloaterIMNearbyChat LLIMFloaterContainer -> LLFloaterIMContainer LLNearbyChatBarListener -> LLFloaterIMNearbyChatListener LLNearbyChatHandler -> LLFloaterIMNearbyChatHandler
