	/**
	* Format a Javascript string, using JSON to export complex values. This
	* function behaves like `sprintf`, except that all the normal conversions
	* (like "%s") will be properly escaped, and additional conversions are
	* supported:
	*
	* %O (Object)
	* Converts the argument to a JSON object.
	*
	* %A (Array)
	* Converts the argument to a JSON array.
	*
	* %b (Boolean)
	* Converts a value to either `true' or `false'.
	*
	* %# (FBID)
	* JavaScript has issues with 64-bit numbers so we use this as our
	* transport mechanism from PHP to JavaScript
	*
	* %J (Javascript)
	* Inserts raw, unescaped Javascript. This is DANGEROUS because it WILL
	* NOT BE ESCAPED.
