Changed the handling of the media library window divider to adjust its width based on the current classic skin scaling if there's not been a manual reposition (this makes things a bit nicer after an initial install & changing to double/triple-size mode without having to immediately resize the divider position either via the mouse or by double-clicking on the divider to auto re-size it to the navigation window)
Fixed using the triple-size mode toggle with classic skins incorrectly triggering the add main playlist into the local library due to a menu item id conflict
Fixed an intermittent crash when moving / changing items in the main playlist due to a lazy loading change in the internal handling with the 1950x/12 builds
