graphics/kvantum: update to 0.17.0

V0.17.0
---------
 * Also, take care of widgets without interior SVG elements on a menu that has a
high contrast with the window (a possible scenario that hasn't happened with any
theme so far).
 * A workaround for a rare problem in QWidgetAction when menus have a high
contrast with windows.
 * Fixed the text color of thin progressbars inside stylable toolbars of
dark-and-light themes.
 * More accurate calculation of spinbox width under special circumstances.
 * Distinguish popup indicators from other button indicators on mouseover.
