  To: Org Mode

* lisp/org-bibtex.el: (org-bibtex-search): New function.
  (org-bibtex-export-to-kill-ring): New function. Export to kill ring.
  (org-bibtex-create-in-current-entry): New function
  (org-bibtex-create): Make it easier to add bib fields to an
  existing headline
  (org-bibtex-export-arbitrary-fields)
  (org-bibtex-treat-headline-as-title): Fix typos
  (org-bibtex-fleshout): Don't upcase optional field; remove ":" from
  type completion

This patch implements several helper functions: exporting to kill
ring, searching only for entries with bib fields, and creating bib
fields in an existing headline. It makes the UI of org-bibtex-fleshout
more consistent.
