Lots of goodies in this one. More work on the default web front page, a few extra utility functions for functions_db as well. Some cleanup in the session code to use some of the new abstraction I added a while back. Player's last login time is now also set on the User object. Issue 28: Forward slashes causing crashes, found by Kuros, fixed by me.
