Change License of gem from GPL 3.0 to dual-license GPL 3.0 and BSD-2-Clause

[tmaier]

Currently, the gem is only available under the terms and conditions of GPL 3.0.

This is quite restrictive, as one could not use the gem within a proprietary software.

This is why I am proposing to dual-license the gem under GPL 3.0 AND BSD-2-Clause

For this to happen, every past contributor must accept this license change.

I would like to ask every contributor to state their support for this license change in this Pull Request.
Simply post "I consent to the license change proposed"

I consent; thanks for doing this the proper way. I am also happy to forfeit any rights I might have on parts of the code, or to follow @inukshuk's suggestion.
