Provide a configuration for an external USB CM Storm keyboard that swaps the
Windows and Control keys automatically when the device is connected.

Steps to install:

1. sudo cp ctrlwin /usr/share/X11/xkb/symbols/
   sudo chmod 644  /usr/share/X11/xkb/symbols/ctrlwin

2. sudo cp 90-evdev-CM-Storm.conf /usr/share/X11/xorg.conf.d/
   sudo chmod 644 /usr/share/X11/xorg.conf.d/90-evdev-CM-Storm.conf

3. sudo -s
   cd /usr/share/X11/xkb/rules
   patch -p0 < evdev.patch
   patch -p0 < evdev.lst.patch

4. Logout and back in so Xorg will re-read the config files in
   /usr/share/X11/xorg.conf.d
