Bug#491602: [PATCH] Populate slime-lisp-implementations automatically

[Torsten Landschoff]

Hi there, 

Attached is a trivial patch to initialize slime-lisp-implementations by 
looking for Debian packaged Common-Lisp implementations on path.

This is far from ideal, but it is a start and it allows me to run 

$ emacs -f slime

to start emacs and get directly into a slime session (provided I have
clisp, ecl, sbcl or cmucl on my $PATH).

Greetings, Torsten
