DiveFilter is not available in Mobile, so another solution
is needed.
Use "for_each_dive_site" to loop over dive sites instead.

desktop-widgets/divelogexportdialog.* contains both the desktop
dialog as well as the "real" export functions.
Create a class to be shared between desktop and mobile
Copy the export functions 1-1 from divelogexportdialog.* of course
changing class names.
saveProfile is highly dependent on the UI, so the implementaion will
be done in each UI directory (desktop-widgets, mobile-widgets).
Remark this commit just add the copied functions, in order to secure
nothing is broken.
