Got tcp receiving for windows done

Callbacks are done - maybe ill add a few more later - i dont know if they will work correctly yet
Fixed the Serialization class
Added internal tags - for now it only has CONNECT and DISCONNECT - maybe ill add more later
Fixed some data type parameters in some functions
