genlist - fix some stacking issues when selecting items with group headers 

stacking become a lot more complex when re-order mode was added, group
headers and more, so simple raise/lower wasn't enough, so this adds 2
stacking markers (rectangles) and objects are stacked above or below
these 2 markers. that basically provides 4 possible stacking slots
that are easy to address, and if you also still raise/lower you get 6
slots. use these markers for stacking so items go into a fixed
stacking layer when they stack around.
