Add formatting correction script

This script is designed to take the output of InDesign's "Export XML" command and turn it into nicely formatted XML. It also cleans up some common formatting problems along the way. Features:
-Fix incredibly stupid InDesign newline encoding (not \n or \cr\n).
-Replace simple & codes (" for example) with ascii characters for easier reading.
-Fix em and en dash usage!
-Get rid of doublespaces
