GPS fix recognition

[neolite]

Hi, first I want to say that sasplanetj is really a great peace of Software

The only thing I miss is a GPS fix notification, I am never shure if the GPS is currently getting a fix or not.

I would be nice to insert somewere a litte SAT symbol:

Red = no GPS fix
Yellow = week GPS fix
Green = good GPS fix

Then sasplanetj would be perfect for me
