Xamarin / Native Windows Phone - Do not continually watch location

[ColinEberhardt]

Watching geolocation drains battery - the GeoCoordinateWatcher should only be started when a location is required

[sh1989]

GeoCoordinateWatcher appears to remember the last known location, which can be queried to determine whether the information is still relevant. I do this in the Xamarin Android project, using any location obtained within the last 5 minutes as acceptable.
