[dev] Adding to the user's session and login credentials

[Adrian Overbury]

This is just a bump, because I can't for the life of me figure out who 
to implement this properly.  I've got the form field for the user to 
enter data into onto the login page templates, but I still need to 
figure out how to make the contents of this field part of the user's 
session object as well as the credentials array that gets passed through 
to the authentication object (and then onto the preauthenticate hook, 
which I think would be the right place to put my actual check).  Is it 
even possible to look at the current session in the preauthenticate 
hook?  If we can't, i suppose I could put both pieces of data into 
$credentials, but that doesn't feel right.  Any help you guys can give 
would be greatly appreciated.
