Maze and Nodes

Added nodes to the maze, also added word gems on maze, placed player and
NPC. Adjustments still need to be made for everything to work.  I added
sight script to NPC.  Gems might need to be raised up a bit. Right now
NPC is not moving. Need to make map camera follow player.  Starting to
look pretty cool though :)
