Tobias Witek 2a35905b89 [themes] Add "cycle" theme capability
It is now possible to add a list of theme configurations in the
"default" section called "cycle". These configuration items will be
cycled through module by module. to create "alternate style" effects.
This is *only* possible in the "default" configuration part, but any
module-specific configurations still take precedence.

Also, removed the capability of per-widget themes. That simply
complicates things and probably doesn't really bring any benefits.
