Hi folks,
I ran into the issue that many others have cited: an inability to add short
titles, etc., to org-mode-generated Beamer presentations [1, 2, 3]. This
patch allows such capability through a BEAMER_HEADER_EXTRA tag, which is
placed after title, author, etc., but before `\begin{document}`. Short
titles, for example, can now be added via
```
#+BEAMER_HEADER_EXTRA: \title[A Short Title]{ \inserttitle }
```
Something like this appears to have been in the original org-beamer.el, but
was not present in the current master HEAD ox-beamer.el. If the
community/BD deems this to be worthy, I'd be happy to clean it up as needed.
Cheers,
Matt
