This patch moves the sort order chooser and options out of the somewhat hidden Settings menu and onto the main toolbar.
We need a real "sort options are here" icon before this can go in, which is tracked with https://bugs.kde.org/show_bug.cgi?id=393318.
I don't consider it a hard dependency, but I'd also like for Breeze to draw a downward-pointing arrow for menu toolbuttons: https://bugs.kde.org/show_bug.cgi?id=344746
