Brand new Grunt task - creates each core library as its own file and a combined phaser.js.

New build script now cleanly splits Phaser, Pixi and p2 so they are each UMD wrapped and each available in the global scope (now more requireJS friendly!).
phaser-no-libs.js allows you to use your own version of p2.js or pixi.js with Phaser. Warning: This is totally unsupported. If you hit bugs, you fix them yourself.
Fixed silly instanceof bug in game objects (sorry guys).
