Added support for multiple hash formats, and new salt generation code.

It selects which hash format to use by checking /etc/auth.conf for
auth_default.  Leaving auth_default disabled will give the current
behaviour (use the same format as is currently used in the password,
or if a new password default to what crypt likes best--des if it exists).
Now you can set it to one of: des, best, md5 or sha1.  best is a synonym
for sha1, currently.
