window: "Hide" edge resistance behind modifier key

Browse Source 
Aligning windows manually with other windows has become less important
since the advent of tiling. This decreases the usefulness of edge
resistance, which in fact many users perceive as lag nowadays.

Account for that by limiting resistance to screen and monitor edges by
default, and only include windows when the control key is pressed.
