Add a License

If contributions and/or forks are appreciated, it would be nice to have a formal license like MIT or GPL attached to the repo.

Very much appreciated, all my plugins are under Apache 2 license (unless specified). I'd really appreciate someone going through them and adding a license file (subtle hint?) :)

teriffic. I'll see what I can do about the Licence-adding :-)
