This patch moves the sort order chooser and options out of the somewhat hidden Settings menu and onto the main toolbar.
Nice-to-haves that would make this more user-friendly in the future:
- Better "sort options are here" icon: https://bugs.kde.org/show_bug.cgi?id=393318.
- Breeze could draw a downward-pointing arrow for menu toolbuttons: https://bugs.kde.org/show_bug.cgi?id=344746
