[TYPO3-core] make class.t3lib_db.php usable for backend modules

[Michael Stucki]

Hi Franz,

first of all I apologize for not telling you this beforehand. I thought it
was clear...

We use this mailing list for a last stop before things enter the Core CVS.
You can submit your patches, write some words why they are needed, and wait
for other peoples go.

However the mailing list is _not_ meant to be another discussion place - we
already have typo3-dev for this. It's just for the stuff that is ready to
be used.

I have some comments here, but the discussion should follow in typo3-dev!

- The name "graytree" makes me think of Volker Graubaum. I'm sorry to say
  but I dislike the idea to make TYPO3 class names a hall of fame, so please
  change it.

- Generally: What does t3lib_db have to do with the list module?

Ah, I see. I don't have a suggestion, but please change it.

I still don't see the sense in it. Maybe you can explain?
