Add a hack to improve menu usability in Alice's Cottage 3

Some screens in Alice's Cottage 3 have menus implemented on the script side. The script does not know the absolute position of the mouse pointer (cursor movement is done by obtaining the relative movement distance of the mouse), so the mouse pointer and the selected item were often misaligned, and the cursor could not be moved by touch operation. This adds a hack to the K3 command that emulates cursor movements by absolute mouse pointer location.
