adaptivetheme 6.x-2.0-beta2

I think we are about there in terms of features, I cant really see anything more I want to see in this theme, so from here on I think we'll only be concentrating on bug fixes and the next phase of development will be looking forward to Drupal 7 and how we can migrate cleanly.

- Adds tweak for the new OpenPublish Subtheme.

- Adds several new theme settings: Menu classes, item list classes, Show/Hide skip nav in a theme setting

- Fix validation issues with taxonomy term lists

- Allow Submitted By module to override comment submitted by information

- Allow DHTML menu module to override menu classes if enabled (required for correct operation of the DHTML module)

- reorder theme settings fieldsets to make more sense to end users

- Fix Article ID theme setting
