[NEW]Backporting the addition of new wiki argument variables, in a single integrated commit made of:
[bp/r49602][NEW]New Wiki argument Variables, to help in scenarios of managing iso9001-powered documentation systems and such, where you need to expose some info like 'last version number', 'last author', and 'last modif' (for wiki pages and/or tracker items) to the wiki page with a special header to include this information. This way, wiki pages can be printed easily conforming the iso9001 document specifications, etc. Ref: http://dev.tiki.org/item5112
[bp/r49719][ENH]Show RealName instead of login name in the corresponding wiki argument variables related to "Author" if the Real Name exists and the preference to display real names where possible is enabled. Thanks diggy, almost the same code you suggested as a patch. Ref: https://dev.tiki.org/wish5112 . Will be backported to 12.x after 12.1 is released. Thanks marclaporte & jyhem for feedback
[bp/r49732][MOD]Changed the way to fetch Real Name to reuse the existing (non-intuitively named) clean_user function. Thanks jonnyb
