#parse_title(title) ⇒ Object

Parse the title from a Favstar RSS title.

title - a Favstar-formatted String (x stars: title here)

This splits on the first colon, and then use everything after that. To account for tweets with colons in them, we have to strip the first “: ” String we find, and then shift the String back two characters.
