Turns text-URLs into working links. This applies to every webpage
Linkifies URLs that are just written in plain text.
Applies to every webpage, so only use it on batches when you need it. Otherwise it can slow down your browser.
If you find a HIT it doesn't work on, let me know (ZSMTurker on www.mturkgrind.com) and I'll fix it. Right now, it's only working for links hosted in
tags.
