deployed minor ui fixes, added some ui animations.

- map-margin-top: 50px (infoboxes are not cut off anymore)
- tried various ways to hide the address bar for android webkit (unsuccessfull)

pending: hook into loading of tiles to render "map tiles are loaded.."
but strangely leaeflet does not support this during initialization (just through panning).

these changes are pending for the current ka-SNAPSHOT.js
