Get rid of crusty old stuff from lib-src.

Get rid of crusty old stuff from lib-src.

We inherited a boat load of stuff in lib-src when we forked from XEmacs,
it's high time we got rid of all that cave-man bit-rot.  This changeset
gets rid of the stuff in lib-src that nobody under the age of 30 has even
heard of, let alone ever used.

	* lib-src/Makefile.am (dist_archlib_SCRIPTS): Removed.
