Allow the {link} tag to accept "mailto:" urls

The current {link} tag only allows URLs in the format of "http[s]://DOMAIN.TLD/mypath", but it would be nice to also be able to pass in URL values such as "mailto:NAME@DOMAIN.TLD".

Great idea, yes we can add that.

Hi Sean, Checked this and mailto links actually should already work. Let me know what error you get when you try them.

OH! I'll check mailto again.
