Remove the grid layout and replace it with code that is derived from the delegate
that we use in the dive list. In order to look proportional I ended up using a
larger font for the location and therefore decided to allow that text to wrap
instead of forcing single line.
This implements a good chunk of another one of Davide's great
suggestions.
