Doug Junkins 27927f74a1 Add export option to export dive sites.
Selecting "Selected dives" exports the dive sites for the selected
dives. Selecting "All dives" exports all dive sites.

XML format is the subsection of the divelog XML that describes the
sites headed with a <divesites> section like:

  <divesites program='subsurface' version='3'>
  </divesites>
