Added BitmapFont to the GameObjectFactory.
Testing BitmapFont as a texture.
BitmapFont moved to extending RenderTexture instead of BitmapData. Now applied as a texture to a Sprite/Image.
BitmapFont fixes and updates and Cache support for it added. Working sweet now.
Couple of new labs tests.
World preUpdate, update and postUpdate have all been moved to Stage. So all children are updated regardless where on the display list they live. Fixes #419
Fixed issue with physics world not being centered if you resized it.
Fixed anchor issue with Sprite.body.
Packaged builds for anyone wanting to test this weekend :)
