Added LICENSE.md

@ssasso @petercrocker @jbemmel:

Added MIT license to the repository (in LICENSE.md). While I like https://github.com/dtf0/wtfpl, it might be "not safe for work" in some countries.

Hope you're OK with that.

I’d not seen that license before, similar to an unlicense but with clearer language ;) https://en.wikipedia.org/wiki/Unlicense

I’m good with MIT, but it’s mostly your code, your call!

Same for me ;)

Added LICENSE.md a long while ago
