[TYPO3-doc] Wiki: all external links with target _blank

[Daniel Bruessler]

Hi,

in the wiki now all external links are automatically converted to target="_blank " links.

This was needed, because the standard in a wiki is, that external links are below in a special section (like wikipedia.org does it)
or clearly marked and do open in a second tab.

You can try it out here

Greets!
Daniel
