There are some errors upon login reported with the current implementation of FML2 & FML3 protocol. Examples: Quark mod (version 410+, FML3), MrCrayfish's Gun Mod (both FML2 & 3). These mods use custom handshakes.
The way to deal with it is to acknowledge any packet from other loginwrapperchannels (from mods). This is enough to login with mentioned mods, but I implement this in try...catch block should it ever lead to an exception in some other unknown cases. Acknowledgments to @letschill, to whose code I returned while implementing this change.
Fixes #29
