Arcade Physics Body.skipQuadTree is a new boolean that if set to true when you collide the Sprite against a Group it will tell Phaser to skip using a QuadTree for that collision. This is handy if this Body is especially large.

### New Features
* Device will now detect for Kindle and PS Vita (thanks @lucbloom)
* Arcade Physics Body.skipQuadTree is a new boolean that if set to `true` when you collide the Sprite against a Group it will tell Phaser to skip using a QuadTree for that collision. This is handy if this Body is especially large.
* Arcade Physics World.skipQuadTree will disable the use of all QuadTrees in collision methods, which can help performance in tightly packed scenes.
