Berthold Stoeger c495a49b1b Cleanup: use getDiveSelection() for shifting time 
There are two cases where dive-times are shifted: in an explicit
dialog and when editing the date/time of a dive.

In each of these cases, the selected dives were collected manually.
Instead use the getDiveSelection() function. Since this returns
a std::vector, change the argument of Command::ShiftTime() to
such a std::vector.
