Dive site: give visual clue for invalid coordinates

Browse source 
On the dive site edit screen, when the user enters invalid
coordinates and saves, we treat this as "no location". This
is rather unfriendly, therefore warn the user with a visual
clue. This is performed by setting the background color of
the widget to red.
