Missing doc authors in Flamingo skin

Hello,
Like I indicated on xwiki users list: on flamingo skin the author no longer appear at the right bottom of pages.

NB: Caty added this precision:

<<In the original proposal of Flamingo Skin http://design.xwiki.org/xwiki/bin/view/Improvements/Skin4x the bottom of pages (#xdocFooter) information were not present. Firstly this is because the proposal didn't covered all possible use cases/views, but was more general.

The information from #xdocFooter:

• can be displayed as in Colibri or
• could be added in the #docextra 'Information' tab.

Since we already display the Tags in the #xdocFooter and document creator is an important information, we should preserve the Colibri display also for Flamingo.
Thanks,>>
