export to beamer: author and dynamic effects are not exported.

[Uwe Brauer]

Hi 

Consider please the following example 

#+TITLE: This title
#+AUTHOR: Uwe Brauer

* This is an example
:PROPERTIES:
:BEAMER_opt: <+->
:END:

Now

    1. This

    2. That 

It should be exported as

\author{Uwe Brauer}
and the dynamic effect as 

\begin{frame}[<+->][label={sec:orge797871}]{This is an example}

But it is not, instead 

\begin{frame}[label={sec:orgb41a8d4},<+->]{This is an example}

Which does not compile correctly

Moreover the author is ignored (there is pdfauthor however which
does not get compiled) and 



I attach the org file the resulting tex file and the corrected tex file

Regards

Uwe Brauer
