HaikuBook: Apply layout customizations after default Doxygen stylesheet

Previously the 'book.css' file was applied as the sole stylesheet for the
Doxygen generated documentation. This stylesheet now applies it as a secondary
stylesheet to override Doxygen's defaults. The main advantage is that when
Doxygen adds new features, they will now be styled by default.

I did my best to clean up the book.css file, though it is not unlikely that
there still is a lot of duplicate CSS. For now though, the output looks mostly
the same, the code blocks no longer have an empty line between each of the lines
and the tooltip text - while not working - are no longer visible on the bottom
of the page.

Tweaks to the API documentation

* Update the Doxyfile for 1.7.6.1. Doxywizard reformatted the comments; that's why this change is so big
* Disable graph inheritance trees; use "Inherits/Inherited by" lists instead (Doxygen has this on by default; I don't think it was intentional)
* Shorten two subgroup names; helps with formatting in Doxygen 1.8 and looks cleaner
* Moves the page footer ("The Haiku Book pre-R1...") be in a <footer> tag, and add a CSS rule for this tag
* Disable XML output, no one is using it
* Disable Microsoft IDL parsing, speeds up Doxygen a bit

Tweak looks of API documentation.

WIP:
* Only a first subset of CSS has been applied
* Look based on Humdinger's and other's work on user guide
* Navigation is still ugly. I need to work around the limitations of Doxygen. Maybe by a patch though.
* Needs a manual extra step: you need to copy the /trunk/docs/userguide/images/logo.png to the /trunk/generated/doxygen/html directory
