apply GPLv2 license to BUSE project (original author must approve)

@comatose,
Please license your code.  I have submitted this same commit in a pull request to the original author (Adam), and he has accepted it.  By accepting this pull request, you agree to license your contributions to Adam's code under the same license.
Without a license, per Berne convention, the author by default holds all rights reserved.  Until Adam accepted my pull request to license under GPL, the only rights we had to his code were granted under the Github TOS (view the code and fork the repo).  In order for me to use your patches, you would have to release them under license as well.
If you agree by committing this pull request, I will as well.  Only then will the lawyers be happy... ;)
Thanks!
