cache: document negative ttls and add about ttl
We've long supported negative ttls, for infinite cache, except the documentation incorrectly showed one of our defaults as being 5 and not -1. As well, with a negative ttl, we were actually making the HTTP expired header go backwards. This changes it to go ahead ten years instead. Further, we add an cache-about-ttl option to set a different ttl for about pages, which are now increasingly being filtered through markdown or just sent statically anyway. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
