Major Update

Added a lot more functionality to the game:
1.  Monster Stink Cloud will now follow the monster until he is dead
2.  The agent will now fight the monster with a sword
2.1 However if the agent hasn't gotten the gold yet then he will exit the
    cave.  This still needs to be fixed.
3.  A bunch of perception messages have been added in.
4.  Updating from the ui is now functional for the agent, monster, gold and sword
5.  Making changes to the start locations doesn't effect the game mid stream
6.  There is a new button added under file open, this allows you to open
    a new .pl database
7.  Restart has been reworked to just restart the state space without askin
    for a file.

With these additions the human wins a lot more often.
