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

CHUI-464, CHUI-466, CHUI-474 : Fixed! Better, unified and more consistent use of refreshConversation() to update torn off dialogs.

CHUI-516: Correcting crash when receiving a god-like teleport lure request while in do-not-disturb mode.

CHUI-484: Updating the code to rather than refer to it as Busy Mode, it now refers to it as Do Not Disturb mode.

CHUI-387 FIXED (Conversation toasts not shown for open conversations when conversation floater is in a minimized state or undocked conversation is minimized): added checking of the minimized state

CHUI-484: Ensuring that the busy/do-no-disturb message is sent when the user is in the busy/do-not-disturb mode.

CHUI-473, CHUI-482 FIXED (Clicking on nearby chat toast to open Conversation floater does not show Nearby Chat conversation selected in list; Nearby chat conversation is not selected in list by default when it is the only conversation ): implement. new logic in LLIMFloaterContainer for the syncronous select the conv. list's item and corresponding convers. floater; removed floater selecting from conv. items; fixed bug with item select

Added audio module initialization without faking mVoiceEnabled value

CHUI-507: Updated to the new layout of 'Chat Preferences' according to CHUI Notifications spec. The functionality for the new preferences is not yet implemented.

CHUI-479: Problem: The parent folder's view model did not store the session id. Because of this, the speaker indicator would be set to a session id of null (nearby chat). Solution: Now when the folder view model is created in the torn off list, pass in the session id. This allows the folder view model to know which session id it belongs to. Participants can then look at the parent folder (folder view) and retrieve the session id.

CHUI-374 FIXED Nearby chat is torn off and cannot be docked if nearby chat is received while conversation floater is closed

CHUI-481, CHUI-404, CHUI-405, CHUI-406, CHUI-407, CHUI-408 : Fixed! Change the way Ad-hoc and P2P chats update their session name in a way which is consistent and honor display name.

This does not pertain to a CHUI bug fix but Richard took a look at the behavior of the layout stack test and found a mathematical bug that caused panels in a layout stack to jitter as they were resized. Submitting in this branch.
