[PATCH] Installing and loading new contrib packages

The new packages in contrib are not installed, and the 
directories aren't in default search path. This patch
does it for nset and pdiff.  

Is this OK to install?  How about the other new stuff?

2003-03-19   David Billinghurst <David.Billinghurst@riotinto.com>

	     * share/Makefile.am:  Add files in contrib/nset
	     and contrib/pdiff
	     * src/init-cl.lisp: Add share/contrib/nset and
	     share/contrib/pdiff to load path
