cli-clock tweaks

Hi user136708,

Rather than writing the GPS lat lon into cliock it would be better to write an app called my location. All mylocation will do is get a gps fix and write lat/lon to mylocation. Json. Then every app that needs your main location can read that. I had thought of doing this myself as I want to add sunrise and sunset to one of my clocks.

Also I wrote a library for gps, called geoutils. Its in gps touch app. I would be interested in extending that with the sunrise sunset calculations based on the value stored in mylocation. Json.
