Create a new allocator

[quackitsquinn]

Writing an allocator was fun, but in reality this allocator is a bit rigid and misses a lot of features other allocators have.

The current allocator has some technical issues:

• Rigid number of allocations, locked to 512.
• Static size, all memory has to be a single block and does not allow for any
  dynamic resizing.
• untested, but the current allocator is pretty slow due to every allocation requiring a O(n) search for a free block.
• Internal implementation is kinda clunky

The new allocator should be a lot more flexible, but what it'll be based on is still up for debate and I still need to do some research on allocators.

Hopefully this will go a lot better than the original allocator.
