fix sendToScreen for QuickTiled windows

two-fold issue
a) setMaximize implicitly sets QuickTileMaximize; setting it again toggles it off
b) setting quicktile mode needs to happen in keyboard mode and thenn the target

still depends on the current windo position, so the untiled window needs to
be in a sane location (while geom_restore will typically be off-screen when
quick tiling by mouse)
