[TYPO3-core] RFC #16031: Feature - Implement new layout and labels for tt_content as result of T3UXW09

[JoH asenau]

This is a SVN patch request.

Type: Feature

http://bugs.typo3.org/view.php?id=16031

Branches: trunk

This is one of the results of team 1 of the user experience week.

It implements a completely new structure for tabs, fieldsets, fields and
labels for the TCE form of tt_content via palettes and types only.
The new structure closely follows the rules we defined here:
http://forge.typo3.org/projects/hci/wiki/Rearranged_page_editing_form

Additionally it introduces so called "formlabels", that enable us to use
different and more verbose labels for the forms, while keeping the default
labels for the rest of the system intact.

Some of the labels are still hardcoded within the TCA settings, but the look 
and feel can already be tested.

To test all different elements, uninstall CSS-styled-content to avoid 
elements being disabled.

German translations will follow.

Cheers

Joey
