[Orgmode] More structure on org-hacks.php

[Carsten Dominik]

Hi,

I just noticed that org-hacks.php on Worg have become quite long, it  
is great
that we have so many little hack there.

I think the file would benefit from a bit more structure (some top-level
headings and the actually hacks as level two headings or so.

Maybe someone would like to do that?
