[Users] FeatureStore filter

[Christian Spanring]

Thanks!

However, I'm not sure if

myvectorlayer.filter( ... )

works with a GeoJSON layer at all, at least it didn't for me. So, what
I ended up doing is rule-based styling with my filter criteria and
basically hiding non-filtered features with

OpenLayers.Rule({
   elseFilter: true,
   symbolizer: {
      strokeOpacity: 0,
       fillOpacity: 0
    }
});

Clearly not the most elegant method, but it seems to work.
