Filter on favorites in offline mode

[twinkle65]

I am using maloo in offline mode, importing all caches using a GPX-query.
On the Filter-screen I now can filter on Difficulty and Terrain and CacheTypes. But it would be great if there was an extra filter-option for the minimal number of favorites.

Compliments for the app!
I come from c:geo and miss my OSM-maps, but for the rest I am a happy user!
