Added a new script to move things back and forth instead of just being hard coded into the platform.  This is the first step for adding more 'spawnables' for the director to handle instead of just platforms (eg enemies, coins, and background art or something)
Changed platforms to be 'spawnables' that are controlled automatically without the director.  Also added for new spawnable called enemy that just moves back and forth and if player hits, they die.
Armor upgrade now increases your health.
Added to ui for how much health is remaining
Added feet object for the player that collides with platforms and made main collider for player much bigger to collide with enemies.  This way collisions no long only revolve around the bottom of the player.
