[Lispweb] Araneida branch release 0.9-a3

Hopefully I'll get a chance to test this sometime!

Quick thoughts:

> * tainted-p, the tainted predicate

Shouldn't this be taintedp? This is convention:

(digit-char-p)
(constantp)

I used to do the same until I was educated.

I look forward to playing with these.
