/*
Implements the 1.4.x protocol classes representing these protocols:
- cProtocol142:
- release 1.4.2 protocol (#47)
- release 1.4.4 protocol (#49) - the same protocol class is used, because the only difference is in a packet that MCServer doesn't implement yet (ITEM_DATA)
- release 1.4.5 protocol (same as 1.4.4)
- cProtocol146:
- release 1.4.6 protocol (#51)
