Also swap the SVGs of view-sort-*
(PNGs have been changed already).

We'll leave them this way for KDE 4, it seems to be the more correct approach - the spec is unclear in this regard, and Tango/gnome-icon-theme have them the other way round, but every other real-life application seems to think ascending is A-Z, which means A top, Z bottom, which means ascending == downwards and descending == upwards.

Strange, difficult, but well.
