Info reader for Clisp



I've hacked on cl-info.lisp so that it can be used by Clisp.  Thus,
describe works on Clisp now.

You need a version of Clisp that has the regexp module.

I've also changed cmulisp-regex so that it can use the same
cl-info.lisp file.

I'm not sending it here since it's rather large, but if you want a
copy let me know.  It's still in an experimental stage, but it works
for me.  It's also much, much slower than GCL and maxima in looking up
items.  But it's better than nothing.
