* Fixed issue in Sound.play where if you gave a missing marker it would play the whole sound sprite instead.

* Button.setFrames will set the current frame based on the button state immediately.
* InputHandler now creates the _pointerData array on creation and populates with one empty set of values, so pointerOver etc all work before a start call.
* Added Canvas.setUserSelect() to disable touchCallouts and user selections within the canvas.
* When the game boots it will now by default disable user-select and touch action events on the game canvas.
* Loaded.setPreloadSprite now rounds the width/height values and starts from 1. This fixes canvas draw errors in IE9/10 and Firefox.
