KPAC Login Redirect Fix

KPAC Login Redirect Fix

Fixes the redirect from the KPAC login to return back to the
home page of the KPAC from the /opac/login screen, rather
than back to the /opac/home screen, which is the current
behavior, and confuses users of the KPAC when they end
up back in the OPAC after having logged in.

Modified KPAC login code to redirect to KPAC after logging in
