*
* Truncates text to a number of characters, but preserves the word. Strips ending punctuation. Will always err on the side of returning more than less.
* Props to alishahnovin at hotmail dot com who posted this at php.net
*
* @param	str		$text	Text to truncate
* @param	int		$numb	Number of characters to truncate to
* @param	str		$etc	Ending. Default is an ellipsis
* @return	str		Returns the truncated text
