Update some things after the switch to git.

- Do not use svnversion to find the version, instead use a revision
  count from git. As a result, the version number jumps back, however,
  so we should have a 2.5 release soon!
- Fix some URLs pointing to either the svn repo,
  or even to google code (!).
