Added a new titlescreen for testing. Run with --module=citadel --level title1.cfg to view. Currently only the Fast Play button is active. Creates random bot and user session id's so the same game server instance can be re-used.  There is still a graphical glitch to fix when we teleport to the new level, in that placement isn't centered. More changes, coming soon... (Eventually the idea is to replace titlescreen with this.)
