demos.css in /trunk/css

Hi all --
It looks like all of the demo pages are referencing 2 stylesheets:
base.css and demos.css. The 3 style rules in demos.css used to be
written to the template page (thanks, Paul, for cleaning that up!),
but now I'm wondering why we don't just consolidate those
stylesheets? If anyone can think of why they should stay separate,
let me know, otherwise I'll merge them.
Thanks,
Maggie
