Network game: Added the code again for NetServerSeqPred.
Work in progress.
Commented out the NetServerSeqPred, since it does not work.
Disabled and added debug print outs.
Merge branch 'master' of github.com:TheJosh/chaotic-rage
Network game: Old server messages handled properly.
The problem was an incomplete copy constuctor for NetMsg,
this made the sequence number invalid.
