Add a "sort role" for sorting the dive list

Browse source 
By default, sorting is done by the display role, but then we end up
sorting by the string we display, which is almost always the wrong thing.

So this adds a new "SORT_ROLE" that is used for sorting, and then the
data lookup can return the raw data we want to sort by.
