Started working on irc

Far from done, needs work
Started 1.8

Broken network code
1.8 stuff

Partially working, something weird with decompression though
Added proof that the last parsed packet isn't the cause
1.8 functionality added!

Still a LOT of work to do, but it can connect now and do basic stuff
again
1.8 is properly working! WHOOO!

world loading is fixed, pathfinding works now, block updates work, and
most of the old 1.7 stuff now works in 1.8!
