faketruth f43b65cf53 cClientHandles have a unique ID now to distinguish them
cAuthenticator uses unique client ID for authentication
Changed the kick function used by cAuthenticator to take a client ID instead of name, so the correct user is kicked
Using callback reference instead of pointer in GetChunkData and affiliates
GetChunkData returns false when failed, and true when succeeded
Renamed entity type enums to something prettier
Exposed some functions to Lua
