adaptivetheme 6.x-2.0-rc1

These release candidates are going to move fast, there are more to distribute testing versions quickly. You can skip these as there will be no important updates and the release of the stable version is imminent (this week, around the 12th Dec).

- added a search-block-form tpl
- cleaned up a validation error for search users (empty dd tag)
- added theme setting for a configurable search info separator
- added classes for search info to theme.css
- cleanup up theme setting comments and fieldset structure for search and comments
- minor css change to the admin theme for messages and comments (added some padding)

Upgrading:
1. Overwrite the beta3 base theme.

2. In you subtheme is to add the new theme setting default to the info file: settings[search_info_separator] = ' - '

Then click "Reset to defaults" in the theme config.

Everything else is the same.
