MouseArea: add source property to mouse event

It comes from the source() of the QMouseEvent which triggered it.
This makes it possible to distinguish real mouse events from those
that are synthesized from touch or tablet.

And for this we need to import QtQuick 2.7

[ChangeLog][QtQuick][MouseArea] Added mouse.source property
to enable distinguishing genuine mouse events from those that
are synthesized from touch or tablet events.
