Subject: Enable incremental updates in PlaceSearchModel

This way pages can be changed without resetting the model.
To achieve this, new members into QPlaceSearchRequestPrivate
are introduced, to keep the relationship between a request
for one page, and the previous or the next page.
In this way sparse population of the model becomes possible.
