prepare_dives_for_divelogs() is based on GTK / C code
where we used GLib methods to generate a temp zip file.
Qt has QTemporaryFile, but it seems there is some sort
of a problem when using with with zip_open
(ZIP_CREATE considered) or at least in this particular case.
To workaround that, we generate a random name ourself with qrand()
and simply pass it to zip_open (with ZIP_CREATE) and then return
the filename.
Also (!), there is memory corruption when trying to return
'tempfile'. This wasn't the case with the C compiler,
to my knowledge. Regardless of this fact the generated
zip does not look corrupt.
