Allow C-c C-c to act on item anywhere on its first line

* lisp/org.el (org-ctrl-c-ctrl-c): Anywhere on the first line of an
  item, act on that item, provided no other object is found under the
  point.  Fix bug when function is called on a footnote definition
  attribute.

This is a convenience feature mimicing old behaviour, but it is an
aberration from the structure POV.
