nodeformcols 6.x-1.4

#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.
