profile: remove AbstractProfilePolygonItem::modelDataChanged()

Browse source 
The old mechanism to replot the profile items was to listen
to model-change signals. Then the code checked whether it
actually had to update anything by looking at the changed
model-indices.

However, the crucial replot was always initialized with
emitDataChanged(), which simple invalidated the full model
and therefore shouldCalculateStuff() always returned true.

Since now the replot() is called explicitly, remove the whole
logic and simply rename modelDataChanged() to replot().
