0.2.0 UI

[Ron Pellegrino <windwardtrades comcast net>]

The project is really improving.  The new UI is a big improvement and I
just love how it updates interactively.  The beagle-settings tool now
works for me when before it would not allow additional paths to be
added.  I can't seem to get Tomboy indexed yet, but everything else
seems to index fine. I tried to index a web page with beagle-index-url
without success, but will have to keep trying as that could be a very
nice feature.  Beagle-search has crashed a couple times upon entry of a
particular search string and so I'm not sure what's up with that.
Anyways, very impressive progress.
