TYPO3 Core

The new skin (t3skin) does not render the table of the User setup quite nicely.

I therefore introduce a patch to make the module tabable with the different groups to configure.

In addition to that, I did the following
- removed the option "wide document background" as it is of no use anymore and should be removed from the core completely soon.
- moved the option "simulate user" into it's own tab "admin functions"
- moved the language option to the personal data tab
- changed the checkbox for the "reset all values" to a submit button

This is just a small change, not the perfect solution yet but way better than before IMHO.
