Renamed srcbase to _srcbase and moved over some functionality to the srcbuiltins module.
Removed commented out includes.
Fixed networked/usermessage dictionaries being read out wrong. Too many elements were read. Furthermore improved the g_debug_pyusermessage convar by indenting the printed message (dicts, sets, lists, tuples) and used iterators when walking through dicts and sets for writing the messages (to avoid converting to lists).
