See also e6e1473e6. The construction of the locationlist
was not the same as the 3 previous lists, and it needs
the inclusion of a new model file (divelocationmodel.cpp)
in the mobile app. In addition, as the mobile app is mainly
interested in a simple stringList (model) to populate a HintsText
field (or maybe later a combobox), this stringlist is added
to the model, to easy interfacing with QML.
