Add GPS icon to the location column for dive sites where we have GPS data

This replaces the really lame "italics text" from commit abe810ca1a29
("Mark locations that have GPS location data attached") with a marginally
less lame GPS icon.There's a reason why I am not making a living as
graphics artist. But I think this is a huge step forward from what we had
before...

The satellite.svg file is very loosely based on a different icon that I
found as public domain here http://www.clker.com/clipart-30400.html.
From that I created the PNG and then that was converted into the
GdkPixdata via gdk-pixbuf-csource; a rule for that was added to
the Makefile but commented out as I don't know if this tool will always be
available in the path. Having this icon included in the sources avoids
locating yet another icon file.

Better icons are certainly welcome!
