setLinks is a small function that will take a string and convert any links or emails it finds to markup.
For example, if you give it this string: 'Here is some random url: http://fr.wikipedia.org/wiki/Lard' it will return 'Here is some random url: <a href="http://fr.wikipedia.org/wiki/Lard">http://fr.wikipedia.org/wiki/Lard</a>'.
Emails will also be processed and converted to 'mailto' links.
setLinksElems wraps setLinks and will do the same to the content of lists of elements.
