new plugin 'jiff_auth' - an alternative to restful_authentication plugin

Hi everybody.
I totally disliked 'restful_authentication' plugin for its need to
generate code, difficult integration into existing models/controllers
and lack of documentation. So, I spent a couple of weeks writing my
own plugin for authentication. Please welcome: http://github.com/snitko/jiff_auth.

All crucial info and howto is in README. PLease join the development
if you like it.
