[Hibernate] Docu update and instructions

[Christian B. <chr...@bl...>]

I just commited the following files:

* New documentation generation instructions, including scripts

* Hibernate style configuration for PDF and XSL

* Updated HTML and PDF documentation, using the new scripts and the
  Wiki CSS

Gavin, redirecting the site is your part. If everythings working out
fine, I will cleanup the documentation directory a bit more and remove
the old pages and unused images and so on...

BTW: The DocBook toolchain is really very painful...
