sky 7.x-2.2

Maintenance Release.

This fixes some small issues encountered in the new 7.x-2.x series including:

- fixed clearing issue in the header (main menu did not clear correctly)
- fixed search submit button, actually changed the style because the old one drove me insane trying to get it positioned in all browsers.
- fixed overflowing text fields in narrow sidebars, had to change the font size (Mac only issue)
- fixed collapsible fieldset legend styles, was showing the drupal core arrows, so removed those
- cleaned up Superfish styles, better font sizes and overall improvements
- removed CSS3 transitions from contextual links, which was bloody annoying
- fixed menu indentation, made more consistent
