Patches from Frode Austvik to modify the effects of the mouse

buttons in several games if STYLUS_BASED is defined: in games where
you can set a puzzle element to 'on', 'off' or 'not yet set', when
it's hard to mimic a second mouse button, it's better to have the
one 'button' cycle between all three states rather than from 'on'
back to 'unset'.
