Changed so that phaser.min is version 2.0.1
Removed the phaser logo.
Has added a background and a platform (although only a floor is
rendered). It also starts the physics arcade engine. It also adds
animation to the character (gravity, a little bounce when it reaches
the end of the world and a sprite sheet animation).
Added character animations for both left and right movement.
Merge pull request #2 from samni698/edit

Adds background image, floor, physics and small animations.
