Disable middle mouse button emulation by default.

The AUTO feature was the default, MB emulation was on until a middle mouse
button was pressed. MB emulation however results in a delay of the first
press, causing minor annoyances to the users and being generally confusing
when the behaviour before a button press is different to after a button
pres.

Disable the feature by default instead. There's not a lot of two-button mice
around anymore though and the inability to detect two-button mice makes for
non-deterministic detection of when the emulation should be on.

Middle button emulation can be enabled with a configuration snippet:

Section "InputClass"
        Identifier "middle button emulation"
        MatchIsPointer "on"
        Option "Emulate3Buttons" "on"
EndSection
