[PATCH] stop using pwgen

[Jason A. Donenfeld]

I'll seriously consider replacing pwgen. I didn't know it was so
horrible. I'll investigate and make a decision.

I like the idea of using /dev/urandom directly, but piping it into
base64 is a terrible idea. I've got some ideas on how to do this. I'll
code a few different ones up and see how it goes. I'll also evaluate
pwgen competitors. There was a nice one somebody on this list proposed
a while ago.

Thanks for bringing this to my attention.
