Really simple fix to add capability to recognize files compressed 
by CRLZH.  Also if file is not compressed (i.e., neither squeezed, 
crunched, nor crlzhed), the LDIR listing says that it is "Stored".  
A minor change to the help display so it looks a little more like 
a ZCPR3 help display.  Plus a minor change to the listing heading 
(HEDING:).
