[TYPO3-core] Filelist "uploads" content element using new FILES cObj (FAL)

[Ingmar Schlecht]

Hi guys,

while working on FAL for the release after 4.7, I've re-implemented the 
Filelist cObj now to be based on the new FILES cObject.

This is the patch on Gerrit (note that it's for the Incubator Git, not 
the real core):
https://review.typo3.org/#/c/9717/

The idea is that we don't use the render_uploads() function in 
css_styled_content at all any more, because the "renderObj" 
functionality of the new FILES cObj offers everything we need to render 
a basic file list.

Here you can find the pending documentation for the FILES cObj:
http://forge.typo3.org/issues/34137#change-103827

Would be cool if you could test it and report whether it's working for 
you. What would specifically be interesting is whether all "Layout" 
options of the cObj behave the same way as before.

By the way, this solution is of course not TypoScript compatible to the 
old filelink content element, but that is also not intended. If somebody 
still needs a compatible TypoScript solution, it's still possible to use 
the old 4.7 static/setup.txt and static/constants.txt of css_styled_content.

cheers
