Title: Added check for invalid retrieved image data in RMWebTileImage

This adds a check to see if a UIImage can be created from the retrieved data, when loading tiles. If not, the request is automatically retried, until out of retries.

This avoids problems with temporary server outages that redirect to an HTML error page, or when on funny networks that drop or mess with connections, like public WiFi that uses captured portals to redirect users to a login screen.
