Altered:
- AMScanThumbnailView::updateScrollBars() ~ Single step for
verticalScrollBar is now 15 instead of 5. Makes scrolling of view less
painful.
- AMScanThumbnailView::mouseMoveEvent() ~ hoverTimer_ time changed from
1000 ms to 200 ms. Makes hover period of thumbnails smaller.
- AMScanTreeView::AMScanTreeView() ~ Sets vertical scroll mode to
perpixel, sets the single step to 20
