Feature request: Press escape to revert window

[goombapatrol]

Could you please include the ability for the 'Escape' key to revert the window to its initial size/position and cancel the drag? Windows by default has this feature, for both dragging and resizing, and it would be great if altdrag mimicked this behavior. Again, this behavior only works from the initial drag, not after you release the mouse button.

Appreciate all the hard work!

Interesting. I did not know that Windows did that.
