  Added Mortens (wulff http://drupal.org/user/7118) panels 3 integration stuff.
Code review from Pelle Wessman (voxpelli)

#532800 Fixed the reference to blocks in the admin http://drupal.org/node/532800 as suggested by jonathan_hunt http://drupal.org/user/28976

#512742 Applied patch from TwoD http://drupal.org/user/244227 to fix the handling of default values in hidden fields. Plus some follow-up changes in the nfcbiblio module.

Make the initial form more consisten to pre-nodeformcols: fix the form weights when there are no nodeformcols settings saved for the node type, change the default region to main instead of footer, added a default high weight for the buttons field and modified the adjustment of new form fields to the buttons.

Leveraging the hooks created for the biblio compat module to support captcha.

Changed the column name 'Main' to 'Main column'. Doing a effort at getting the field title for form elements.
