`fdroid --version` for installed releases and running from git

This will report the version embedded in the module if it is installed, and
will report `git describe` if being run from git.  If someone installs from
git using pip, this will probably report the version in setup.py, which
will be wrong.  But that is not a documented install method, and I haven't
heard of anyone using it.  The recommended way is to run straight from git.
