LibGUI: Make model sorting imperative and move order to AbstractView

Browse source 
Instead of SortingProxyModel having a column+order, we move that state
to AbstractView. When you click on a column header, the view tells the
model to resort the relevant column with the new order.

This is implemented in SortingProxyModel by simply walking all the
reified source/proxy mappings and resorting their row indexes.
