Creation of net.meltdownstudios.scl.network.client for LocalClient and
LocalClientManager classes. Added support for chat room tracking with
LocalClientManager and LocalChatRoom.
Added convenience function .isLocal() to ClientManager.
Added ChatRoomInfoAction to provide the client with pertinent chat room
information upon creating/joining.
Updated ChatRoomChange/ResponseAction to notify the
LocalChatRoom/LocalClientManager of chat room changes (so state is
always correct).
Logged in state now tracked by the LocalClientManager as LocalUser and
in LoginResponseAction.
Registered ChatRoomInfoAction to the client network action manager and
modified.
