//Carl: Added jquery functionality to replace status box without a postback.
//Carl[1.13.2009]: Added a modal dialog (thanks to Eric Martin's SimpleModal plugin) for retweets, instead of using the Twitter status bar.
	//This allows for retweeting from any page on twitter, not just ones with a textbox at the top (ie. Favorites, etc)
