X11 install

Build and install the NetHack.ad file, and change the nethack.sh to append
the HACKDIR to the XUSERFILESEARCHPATH.  This means users do not have to
do anything special to use the NetHack X11 resources, nor does it require
teaching nethack where the X11 app-defaults directory is.  The change also
updates the X11 and linux doc files in a corresponding way.
