License change from GPL to BSD

[Cinc-th]

I'd like to change the license to the more permissive BSD license. This better aligns with the Trac licensing and may help code reuse (most plugins on Trac-Hacks use BSD afaics). My own code was under this license anyway.

To minimize necessary rewrites I want to ask if it's ok to change from GPL to BSD for the code contributed by rjollos (a ton of fixes and refactoring) and falkb (most of the code in the version modules in version.py, a lot of other code sprinkled in other files).

Code from the original author(s) is mostly gone during the last 8 years or will be rewritten anyway while bringing the codebase to Trac 1.2+/1.4+ and 1.6+.

I fully support the change.

You may use the Blame feature in the source browser to see the authors for different code additions.

OK, the license change is fine with me, too.
