Allow black background (again)

Please allow the black background in the viewer. This allows much better contrast to see the protein atoms without being distracted with the background image. This was the way the old FAH software looked (v5.03, ~2005):

Given my current issues with the background image being low resolution, this would be a welcome option.

This can be set with the launch option --background none
On Linux this is set either by running the viewer manually, or by changing the "Command" variable in the visualization area of the preferences menu. Unsure if this works the same way on windows, but I suspect it will be similar.

EDIT: Additionally, you can set a higher resolution by specifying the file path to the image instead of none in the launch option. The FAHViewer help page states that this only supports the PPM image format. From what I can tell by reading on Wikipedia, this file format results in very large file sizes, and I cannot recommend using a high resolution background.

Thanks for the hidden feature info, which does work the same in Windows.
I would still like to be able to toggle the background on / off with a keystroke listed in the GUI help in a future version of the Viewer.
Additionally in the FAH Advanced Control preferences, it would be good to have a checkbox that sets the new viewer help option (or adds the extra command line parameters), since that would not be obvious to the average user.
