[PATCH xrandr] Allow -x and -y switches to undo themselves

[Connor Behan]

People who want to dick around might think it is safe to run "xrandr -x"
before they know any of the other syntax. When "xrandr -x" again does
not get back to a normal screen, they are stuck having to read a manpage
with reflected text.
