More auto for lists

[awalterschulze]

In chapter 13 of Coq Art, we see the use of the following tactic:

autorewrite with llists using auto with llists. 

I suspect this does more rewrites that just using autorewrite, but it would be good to investigate if this is better than auto with list or 'autorewrite with list` in CoqStock.

See

See if examples are proven easier with this tactic or create proofs that are show that this tactic is superior in some way and add a comment explaining.
