Merge StatusSortFilterProxyModel into TransferListSortModel

I thought merging all 3 sort-filter proxy models into one should
speedup dataChanged() signal. As turned out this is not the case. The
time difference is within inaccuracy range, so this doesn't affect
performance.

But I still think it is good to merge them into one proxy model as it
simplifies code.
