Releases for Chaos tool suite

This release fixes several bugs, plus introduces a couple of nice new features. Changes of note:

• The "page elements" content types were broken if you used more than one. They have also been improved.
• Variant import did not work at all.
• Views panes got a bit of a settings makeover.
• Search, contact, blog and poll pages are now offered as system pages. This should be all of the user-facing pages core offers.
• For develepers, we offer a backport of the drupal_static() function from Drupal 7. In the future CTools may offer backports of simple core functionality from D7, at least until D7 is ready to go.
