A few "problems" with r758

1) If you hook OnGetNexPacket before login it'll crash the client upon login.
2) If you unhook OnGetNextPacket the client will crash.
3) The addresses for OnGetNextPacket and RecvStream were including in
Core.cpp because I couldn't get it to work by sending the packets through
the pipe. (I believe the problem is with pRecvStream(?)).
4) Before I changed the OnGetNexPacket parser into multiple switch cases
the client would crash upon floor changes. So far I haven't had any
problems, but it seems to lag the client. Maybe this could be fixed by
putting the parser into it's on function on a seperate thread? (I have no
clue how to do that by the way).
5) Without also hooking Recv, Send didn't seem to work so it was commented
out and therefor we can't check outgoing packets. If someone wants to
retest hooking Send for me then I would appreciate it.

I think that's all the problems I can remember. The reason for this commit
was because the parser for Recv wasn't working right and the packets
weren't being parsed correctly resulting in inefficiency of packet events.
I've tested several packet events and they all seem to be working great
with this method. If you have any questions, concerns, etc. please reply.
