[Bug 4777] Mouse Absolute vs. Relative Incorrect Behaviour (doesn't match Windows)

An "easy" fix would be to do this:

In function alloc_device(), add:
newDevice->absolute = 1;

In function SysMouseAImpl_SetDataFormat() remove:
This->absolute = 0;

However, I'd imagine this would require testing to make sure it doesn't break existing stuff. This 
change does seem to be in accordance to how Windows works, but a comment in the Wine code seems 
to contradict this:

402     /* Tests under windows show that a call to SetDataFormat always sets the mouse
403        in relative mode whatever the dwFlags value (DIDF_ABSAXIS/DIDF_RELAXIS).
404        To switch in absolute mode, SetProperty must be used. */

Obviously, this is NOT the case for Myth II, because Myth II does call SetDataFormat, and Windows 
doesn't keep re-centering the mouse there.
