Filter: reload only when checkstate changed

Browse source 
Currently, the filter is recalculated if a filter-entry is changed.
This also happens if the counts of a filter-entry changes. This
is to be avoided, as it causes unnecessary churn.

Therefore, send the proper role with the dataChanged() signal
and add a new slot, which invalidates only if a field with the
Qt::CheckStateRole is changed.
