[PATCH] Extra Command Line library functionality (option grouping and runtime inspection/modification)

[Daniel Liew]

I realised my naming of the default option category wasn't such a good
idea (a category called "Default" is confusing) so I've amended my
first patch so that the default category is called "General".

The amended patch (001-amended.patch) is attached. I should also note
that patch 001 needs to be applied before patch 002.

Thanks,
Dan.
