allocator

The allocator that will be used for everything in this networking library. This will primarily be passed onto NPC and Player info objects, which will utilize this to precompute extended info blocks and the overall main buffer. It is HIGHLY recommended to use a pooled direct byte buffer if possible. Pooling in particular allows us to avoid allocating new expensive 40kb buffers per each player, for both player and npc infos, and direct buffers allow the Netty layer to skip one copy operation to move the data off of the heap.
