Fixing the docs!

Unfortunately the handbook got scrambled when d.o. upgraded to d6. See http://drupal.org/node/376790.

As mentioned in the issue the work is ongoing and hopefully the docs are fixed soon. mitchell and me thought about doing our on documentation site in the meantime or forever, but I think it's better to stay on d.o. - so people can contribute faster, without the need for registering or even logging into another site.. (Yes, every d.o. user can contribute to docs).

It looks like the hierarchy is reset back once it's fixed. If the fix isn't working right, it's going to be scrambled again. So I think the best thing we can do now is linking all pages on the rules documentation starting page. So please help finding all pages and linking them there!

Also improvements to the docs are very welcome.
