Hello worgers,

I've noticed that all links to raw files (.el) on
http://orgmode.org/worg/org-contrib/index.html are broken. They used
to be pointers to repo.or.cz. The attached patch reactivates these
links with pointers to the new orgmode.org git repository.

This is my first patch (not to worg, but ever), and I'm still learning
how to use git and so on, so please tell me how I could make better
patches in the future.

BTW, org-contrib/index.org needs an update on a few additional
points:

- A few new contributions in contrib/lisp are not listed here.
- A few contributions passed into the core of org. This should be
  commented, together with link to the relevant sections in the
  documentation (org.texi), etc.
- A lost last version of org-refer-by-numbers.el
- A decision to take with links to raw-files that were removed from
  the org-mode git repository: either link them to legacy raw file
  from org-mode git, or remove these links
- and a few other tiny things...

I would happily take care of that, or help anyone in doing it. I
welcome any advice on that.

Thanks for all your job in org and worg,
A happy Org user,
François.
