DiveObjectHelper: Turn DiveObjectHelper into Q_GADGET based object

DiveObjectHelper is a tiny wrapper around dive * to allow access
to dive data from QML and grantlee. It doesn't have to be a
full-fledged QObject with support for signals, etc. Therefore,
turn it into a Q_GADGET based object. This allows us passing the
object around as object, not as pointer to DiveObjectHelper.
This makes memory-management distinctly easier.
