Minor Jonah and Sugarcane fixes.

* Added missing String.unDash() function used by Wikifier.formatHelpers.inlineCssHelper - see also http://www.glorioustrainwrecks.com/node/5063
* Altered the "macro" formatter lookahead regex so that single greater-than signs are permitted inside macros. (Double greater-than signs still terminate).
* Added <noscript> messages to alert the reader that Javascript is off.
* Removed Furl link from Sugarcane.
