Made Ctrl-Alt 9 the hotkey for the new hq3x scaler, and moved the scanlines

and dotmatrix ones to Ctrl-Alt C and Ctrl-Alt-D.

(Does anyone else feel that scanlines and dotmatrix should either be
rewritten so that they can be combined with any scaler and aspect ratio
correction, or removed? That's why I moved them off the Ctrl-Alt <digit>
hotkeys.)
