Git migration

I have finally migrated all of my software to git. This was not a very fun process due to the nested nature of my "drobillad" repository, but now all projects live in their own git repositories with history and tags from SVN preserved.

It is still possible to build all my audio software in one step, the top-level repository http://git.drobilla.net/drobillad.git is now a skeleton with git submodules for each project. Anyone using SVN should switch immediately, the SVN repositories will remain in their current state for the foreseeable future but all development activity will move to git.

All the repositories are available in cgit, but changes and tickets and so on are in Trac as always. Happy hacking.
