Windows 10 1809 WSB update and Dark Mode Style Script

[blaubart]

Meanwhile replaced all FILLCOLOR with images in ThumbButton horiz/vert + left/right/upper/lower Track also in
"Buttons, Boxes, & Controls > Scroll Bars & Trackers" (org, not DarkMode) like Aero does. No problems, works as it should.

This would not have been possible without learning from your unbelievebable work the last years. Thanks so much and keep on fighting, 1903 will come soon...
