#1 Patch (0.5.8) to use MD5 hash passwords

[Ben Finney]

Storing passwords in cleartext gives me the willies, so
I've made a patch to store and authenticate MD5 hashes
instead. The code, tables, and READMEs have been
patched. I hope you'll consider putting this into
the mainline code, since it makes sense for just about
all installations.

I've made patches against bplog-0.5.8 and
bplog-20020105, they're attached. They're also on my
webpage at:
