Add a LICENSE.md

[fry-]

Even though the source code is open, it's not clear under what license it is.
So far (without a license notice), it's proprietary and under the rules of strict copyright ownership by "the contributors".

I suggest adding an open source license (preferably GPLv3 or MIT in my point of view).
Here is some resource on that topic:
Open Source Initiative - list of popular and approved licenses
Wikipedia - Comparison of free and open-source software licenses
gnu.org - how to choose a license

Vote for GPLv3 :)

As the project is currently tightly integrated with BWAPI, which is LGPL 3, I assume it has got to be compatible, so I'm gonna release a fork under GPL3! SUE ME!
