Build Simplification

Moved GCC 4.8 and dependencies (except libmysqlclient for now) into the main directory, eliminating a lot of absolute paths in the build system.
0x33 Tweak

0x33 packets are now partially built on the stack, saving a heap allocation/deallocation, and probably increasing access speed (no indirection) each time a 0x33 packet is built.
Hash Header Fix

hash.hpp was missing #pragma once.
Makefile Cosmetic Fix

Makefile had a spurious pipe character.

No affect on functionality, poor form however.
