Recently we changed the MapLocationModel-items to store whether they are selected. Thus, we can directly export an isSelected flag instead of calling a function taking a dive-site argument. 1) This makes the QML easier to read. 2) This avoids passing pointers through QML which has caused us lots of pain.
