Subject: [PATCH] org-beamer.el: Enable custom beamer input before
 \begin{document}

* lisp/ox-beamer.el (`beamer-header'): Move BEAMER_HEADER injection to
  final part of preamble (after themes, title, etc.). Allows for
  custom short titles, etc., with #+BEAMER_HEADER: \title[Short]{Long}.

Previously, TITLE was being injected after BEAMER_HEADER, so short
titles (and related) could not be added. BEAMER_HEADER now serves as a
final preamble injection point.
