BlackHalo - Smart Contracts

The first commit of Halo contains BitMHalo. This is a custom Bitmessage implementation for running messaging and decentralized markets in Halo. This is basically the backbone of communication and it is how the markets and communication are kept private and serverless.‌‌BitMHalo for now, uses a series of locking files. BitTMP is what Halo generates with the current command. Other commands are held in a file and this is done without making RPC calls to avoid losing pending commands. There is a more efficient way to do that but until a Halo refactor is done then this is the protocol. So Halo (either BitHalo/BlackHalo/BitBay) must be running for BitMHalo to have any use. This can be made more object oriented and logic separated. Also we could use more threads. It should be noted that Bitmessage doesn't behave properly when run outside of the main thread. This is why the decision was made for it to have it's own binary. Also this helps when permissions are being asked for an entirely separate P2P protocol.
