iMore menu changes: reworked Mobile Find menu to look more like Desktop, with the text search box at the top level, POIs at top level, and other options removed.

Added ability for a text search to "look like coordinates" and zoom the map.
Geocoding will now check that the resulting point is in fact within the MAX_BOUNDS and will not zoom the map if it's out of the area. This addresses nonexistent or wacky results such as "post office" returning Post Office, India.
On a search, if no Cleveland results are found, the behaqvior is changed.
It will no onger show the "Do address search" link, but will simply perform the address search for you.
