Replace UUIDs from LocationInformationModel and fix the fallout. Notably, replace the UUID "column" by a DIVESITE "column". Getting pointers through Qt's QVariant is horrible, we'll have to think about a better solution. RECENTLY_ADDED_DIVESITE now defines to a special pointer to struct dive_site (defined as ~0). This fixes an interesting logic bug: The old code checked the uuid of the LocationInformationModel (currUuid) for the value "1", which corresponded to RECENTLY_ADDED_DIVESITE. If equal, currType would be set to NEW_DIVE_SITE. Later, _currType_ was compared against _RECENTLY_ADDED_DIVESITE_. This would only work because NEW_DIVE_SITE and RECENTLY_ADDED_DIVESITE both were defined as 1. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
