[refactor] Remove the word 'Manager' from most source files/namespaces
ChatManager -> Chat MissionManager -> Missions NanoManager -> Nanos TransportManager -> Transport ChunkManager -> Chunking BuddyManager -> Buddies GroupManager -> Groups RacingManager -> Racing ItemManager -> Items NPCManager and PlayerManager remain. Note: You can use git log --follow src/file.cpp to trace the history of a file from before it was renamed.
