Work on Authentication System(s)

Login_Handler can currently use one of two methods. LDAP, or unix style authentication.

Unix style authentication parses a file formatted like /etc/shadow. Yeah, you can use /etc/shadow... our program is already running as root anyway :S
LDAP style authentication attempts to bind to an LDAP server.

If Authentication is successful, the key generated by FCGI_LockControl is passed to the browser as a cookie.

In the FCGI_Loop function, we check for a valid key in the cookies.

I've tested LDAP using a LDAP server I setup on my laptop.
We may have issues formatting the DN correctly, but other than that it's fine.
