    Add customization to present chat room name after incoming message
    
    The default behavior is unchanged. Users who would prefer the chat room
    name be presented after the incoming message rather than before can
    accomplish this by adding the following lines to orca-customizations.py:
    
    import orca.settings
    orca.settings.presentChatRoomLast = True
