CHUI-799 FIXED Notification is not given to user when they select only friends and groups can IM me preference

CHUI-778: Now when changing paths for chat logs and transcripts any empty conversations will be reloaded with data from the new location. Use case for this is if the users nearby chat is empty and they switch to a location that has a nearby chat file, then the nearby chat file be loaded.

CHUI-778 (Saving preferences updates text in all open message panels in conversation floater to show as old messages) Now changing the log/transcripts file location actually moves the files to the new location. Prior behavior just started a new history at that location. Also a fix was made so that if the user changed the log/transcripts path then after pressing the Preferences 'OK' button the new location will be saved to the corresponding .xml file.

CHUI-778: Minor changes, prior commit was not changing the file path correctly due to logic error. Also clicking the 'Cancel' in preferences would still cause the file location to be saved instead of ignore the save.

CHUI-778 (Saving preferences updates text in all open message panels in conversation floater to show as old messages) Problem was that closing the preferences floater was always acting as if the conversation transcripts/log files path had changed. If the path did not change then the user's conversations would be cleared and re-loaded as if they were part of the user's history (causing text to be grey). Solution: Now keep track of when the path was changed and only load up the transcripts/log upon change.

CHUI-668: Now when exiting DND mode, the user's most intrusive notification will be used to notify that user (if received IM's during DND mode). Nearby chat messages/settings are ignored.

CHUI-668: Not fully complete but as of this commit, have functionality to use the user's most intrusive chat notification upon exiting from DND mode with IM's. Also if in DND mode, clicking on a conversation line item or floater, will flush the DND notifications system of storing that conversation. This way upon existing DND mode already responded conversations won't be notified to the user.

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:

LLNearbyChat -> LLFloaterIMNearbyChat
LLIMFloaterContainer -> LLFloaterIMContainer
LLNearbyChatBarListener -> LLFloaterIMNearbyChatListener
LLNearbyChatHandler -> LLFloaterIMNearbyChatHandler

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

Path-643. Once the preferences panel is closed (either through ok or cancel), the pathing console rebuilds the gfx data.

EXP-1942,EXP-1945: Altering behavior when setting maturity preference to check the server response in an effort to ensure the viewer and server remain in sync.  This is a partial commit as I still need to add user behavior and notifications when things go wrong.
