qmlmapwidgethelper: maintain an instance of MapLocationModel

Browse source 
The idea here is that the QML code should be able to fetch a model
from the MapWidgetHelper instance which is instantiated inside the
QML code; fetch it in the lines of "mapHelper.model".

This way, updates at the backend would be reflected on the Map QML widget.
