Made FieldInitializer to replace Components in initializing data fields
Working physics implementation - added revolute joints and a TexturedSolid preset
Made a test pendulum balancer
Added basic fluid physics - very slow
Liquid work in progress
Merge branch 'master' of https://github.com/spfrommer/big-phage
Integrated bump mapping into engine
Made a pendulum balancer which brings the pendulum to rest
Added a base PhysicsGame class for simple games and rewrote PendulumTest

PendulumTest now uses controllers balance the pendulum and move it based on keyboard input.  In the 
future, PhysicsGame will extend from a Game class.
