Mouse method move(xoff, yoff) doesn't work as expected

[trots]

Method Mouse().move(xoff, yoff) move cursor to an absolute position (xoff, yoff). But it should do offset from the current position.
I think this line

lackey/lackey/InputEmulation.py

Line 43 in 1ea404a

mouse.move(xoff, yoff)

should be replaced with

mouse.move(xoff, yoff, absolute=False)
