This is a formal request to integrate my org-html.el & org-odt.el
changes in to the master branch. 

This patch introduces 3 major features:
1. A generic exporter
2. All new html backend re-implemented as a plugin to (1).
3. A odt backend as a plugin to (1).

The patch is based on git commit 3d802.

I am attaching a sample test.org and test.html file generated by the
above set of changes. 

Http URL for the repo is:
- http://repo.or.cz/w/org-mode/org-jambu.git/shortlog/refs/heads/staging
(`staging' branch of `org-jambu.git')

Let me know if you have any questions. 

ps: Considering the amount of effort I have already invested in these
patches it is almost impossible for me to break down this monolithic
patch in to series of smaller patches. I would be willing to accommodate
all other requests.
