Implemented note block playing and fixed wire

Game of Thrones music in Minecraft, here I come!
Added SendEntityEffect and SendRemoveEntityEffect. Also a Player now gets the hunger effect when he has food poison.
Forgot to commit the ClientHandle.
Wires no longer power if a block cuts them off

Also reduced more unneeded code.
Potentially fixed debug asserts

Implemented note block playing and fixed wire
Added E_EFFECT_<Effect>
Exported E_EFFECTS_<Effect> to lua. Forgot to commit Globals.h.
Removed leftover debugging messages from cProtocol172.
Added tolua++ redirection include.

This is needed because ToLua++ regenerates the Bindings file with bad #include, and it would be too difficult to fix ToLua++; this is an easier solution.
Should fix PR #431.
