add target for removing extraneous whitespaces in the programlisting tags (thanks Fabien) 	                         	SIDE EFFECTS:                              due to the way XPath works it also removes DOCTYPEs and comments  that are not inside the root	node         (ex: comments at the beginning or end of the file)

due to the way XPath works it also removes DOCTYPEs and comments  that are not inside the root	node         (ex: comments at the beginning or end of the file)

The way the doc is structured right now the only file that contains the DOCTYPE is PA_index.xml. However PA_index.xml does not need to be formated (it is listed as excluded in the ant target).
