This allows X applications to be run on wayland without having to<br>
delete conf files needed to run the legacy X server on the same<br>
machine.<br>
<br>
The --config and --configdir switches can override these changes.<br>
<br>
An extra patch to xorg was needed, as it *always* looked for<br>
xorg.conf.d. I changed it to not do this if --configdir or<br>
--wayland was given.<br>
