geoqo-0.97 released

It's been quite a while since I've made a geoqo release. A few new
things and a number of bug fixes have been put in place. I'm trying to
work to a real 1.0 release, but I haven't had the time lately to sink
into the tasks I want to complete to make that happen. Here's the NEWS
about 0.97:

New in version 0.97:
- A new import plugin "dir" for importing an entire directory of files
- Database searching using a track can now use data beyond a given date/time
- A number of small bug fixes. In particular parts of the GUI were broken.
