Adds classes to merge a template qml file and a qml stylesheet that have
been exported from other design tools into a resulting qml file that can
be used for further processing in Qt Design Studio.
Current issues:
* Sometimes it makes sense to define width and height
if an anchor is present, but most of the time not.
* Actually if the hierachy was defined (e.g. Text item not child of
background) most likely the anchors should be ignored.
But this would be just a "dirty" heuristic. I suggest to let the
template decide. If the template has anchors those have "precedence".
It is always possible to define templates without anchors.
