Fixing the arandr issue which depended on all modes to have a <width>x<height>
name.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507521
Changes while running are not caught.
- Versions before 0.1.7 depended on all modes to have a x name (see debian bug #507521); if ARandR does not start up, please install the latest version. (On different bugtrackers, this is called the ValueError / "1080p" / "1024x768i" problem).
- See TODO for planned features.
