mobile/divelist: better handling of selection change

This still has an odd bug. When we swipe the dive details to change the
selected dive and that action causes a trip to expand or collapse, then
the color change / highlight in the dive list isn't updated correctly,
even though the log file indicates that we made the necessary changes.

This also changes the coloring of the selected dive; having the same coloring
as a trip was very confusing. This is a bit stark, but it clearly communicates
the distinction.
