[Orgmode] New beamer support

[Sébastien Vauban]

Hello all,

Here a few comments, after my first attempt with the new beamer support --
excellent, needless to say...

Before that, I was using Nick's export class. But, now, I'm using yesterday's
git version.

The few things I'm tackling right now are:

- How to get a TOC with a frame title, without having to add it explicitly?

- How to get alerted text, without customizing `org-export-emphasis-alist'?
  Has this been forgotten from the commit?

- How to get "frame breaks", without modifying the resulting TeX file (by
  adding a frame option `allowframebreaks' -- similar to the `fragile'
  option)?

- How to get the TOC repeated when changing of section, with the new item
  highlighted?  See my manual essay ;-)

The last question has maybe few to do with Org. I mean: maybe, we can't have
that feature implemented in Org. Dunno.

Here follows an example to play with, and see what I'm talking about:

* Context

** Context
   This document is a minimal example, full of fake sentences:
   - the list of assets currently found, and
   - the things that *must*, /should/ or @could@ be developed in the coming
     months.

   Is "could" presented as an alert?

   Note that the previous slide, TOC, has a title, because I inserted it
   myself. When generated by Org, there is no frametitle.


* Current assets

** DB
*** Model
**** Schema
**** Partial X
     We extended X in order to put constraints on things (as one can
     with cardinalities).
**** What
*** Rules
**** Other
***** First
***** Second
***** Rules, with link automatically made between rule failures and 
contributing properties
**** Performance
***** Specialization of programs given partial data
***** Query reduction: optimize the queries so that with a minimal IO 
interaction the necessary data from a DB can be requested
*** Computations
**** Excel engine *IS NOT THE LAST ITEM*
*** Integrity *has a subitem* (not shown by default)
**** Seamless migrations is not visible if allowframebreaks is not set

** Workflow
*** Petri net engine
*** Workflow viewer
*** Data mining
*** Internal engine (based on new protocol)
*** Semantic language (integration of the model and of the other stuff)


* Future developments
#+BEAMER: \frame[c]{\begin{center}Future developments\end{center}}

** Model
*** Extensions (aggregation, negation)
** Workflow
*** Workflow editor
