Tilemap.getTile and getTileXY used to return `null` in 2.0.3 but returned a Tile object in 2.0.4 (with an index of -1), they now return `null` again.
ScaleManager seeds _check private var with null to avoid later comparison check (thanks @jflowers45, fix#782)
P2.Body.applyForce should have used pxmi instead of pxm (thanks @Trufi, fix#776)
P2 fixed creation of RevoluteConstraint by passing maxForce in the options (thanks @woutercommandeur, fix#783)
Merge pull request #783 from woutercommandeur/dev
fix creation of RevoluteConstraint by passing maxForce in the options
Input and Pointer now use the new ArrayList instead of a LinkedList, which resolve list item removable during callback issues.
Input.reset no longer resets every interactive item it knows of, because they are removed during the destroy phase and can now persist between States if needed.
Game checks if window.console exists before using it (should fix IE9 issues when dev tools are closed), however it is still used deeper in Pixi.
Body.loadData flagged as deprecated.
Emitter.particleAnchor allows you to control the anchor of emitted Particles. Defaults to 0.5 (same as before) but now under your control.
Emitter now emits Phaser.Particle objects instead of Phaser.Sprites, which can be extended as required.
Emitter has had various local properties removed that were already declared in Phaser.Group which it extends.
