Migration to GitHub

In the last few months I've been quite busy working on the prototype of version 2.0 of WebIssues. My plan was to reach a point where the new web UI is functional, at least in the most important areas, before migrating the code repository to GitHub. However, with the recent series of outages and problems with SourceForge, I decided not to wait any longer. Honestly I don't blame those guys who work for SF. I suspect that these problems have more to do with politics than with technical reasons.
