Title: Tile cache and zoom

Sorry that it is late for this to arrive, but there were some quirks to address.
Finally I am relatively satisfied with it.
Whats in it:

* refresh on zoom in, especially necessary for fast strategy. At the same time there is a cache for the last searchByCoords-Area to avoid re-downloads.
* tile cache, avoids unnecessary re-downloads on map move
* Added test for AutoZoom calculation, fixed tests (all green!)

Take a look and then decide if it should go into this release or the next.
