Subscribe to the game/table topic, and the pocketcard/personalgamestatus
queues.  Add seat directive and template that for now just displays the
username of the player and their chips.  After a 5 second delay after
all the players have joined, send out a table update.
Remove the use of the database, which really only affected the game and
user objects.  Both objects are now just being stored in in-memory
hashmaps.  Security has been changed to inMemory as opposed to jdbc.
