Add 'Save As' entry to context menu shown when right clicking on a dive

Something which is nice especially when asked on the list to share an
interesting dive is the possibility to save just some dives into a file.

This commit adds to the context menu shown with right-click the 'Save As'
entry. This entry allows to save selected dives.
