Changed "exit on suspend" behavior

In config.xml, Exit On Suspend is now false, so the app will continue
running by default. In my development, exiting and restarting is bet
done by reinstalling anyway.
Bing Locations API (geocoder). Settings button.

Added the geocode() and geocodeAndZoom() functions to library.js, for
easy access to Bing's geocoder and the most common use cases.

Cosmetic enhancement to the Settings button, so it now fits in with the
Leaflet buttons.

Turned off Imagecache.options.debug
