Add current time and adjusted time to gui when adjusting dive's timestamp

This patch adds the current dive time and the adjusted time to the time
shift window. I added a function to dive.c to get the timestamp of the
first selected dive.

This will view the time of the first selected dive only even when multi
dives are selected but it does change the times for multiple dives
properly.
