/* The above code will remove hex copntrol cahracters from a textarea, needed with firefox for some reason.
	functions used are:
		escape 	- The escape() function encodes special characters, with the exception of: * @ - _ + . /
		unescape - decode strings encoded with escape	
		setCaretPosition - find the last text position and set the caret (cursor) after that character
		trimText - drives the process by finding the control characters and replacing them with a null
