Relicense to MPL-2.0 for upstreaming
I'm not sure exactly why I chose a different license in the first place, probably because I didn't consider that these hacks could be upstreamed eventually. But now that some of the configurations in this repository would actually be useful upstream, most noteworthy fixes to about: pages that make them more adaptive, let's relicense to MPL-2.0 and begin the upstreaming process (#28).
Everybody who contributed code, is it fine with you to do the license change? Please reply here in the issue.
