Dragging a Sprite while the camera was moving would slowly cause the Sprite position to become out of sync the further the camera moved. A Sprite being dragged now tracks the camera position during the drag update and adjusts accordingly (thanks @jeroenverfallie phaserjs#1044)

 * P2.World.updateBoundsCollisionGroup didn't set the `_boundsOwnGroup` private var, meaning the `World.setBounds` method wasn't able to restore previously set collision masks automatically (thanks @jmp909 #2183)
 * P2.World.setBounds has been re-written completely. If the World is resized it no longer removes the P2 body instances and re-creates them. Instead it checks to see which walls are required and then just moves the position of the shapes instead, or updates them, or creates or destroys them as required. This is far more efficient, especially in a game which sees a lot of world bounds changes (i.e. resizes responsively in browser)
 * BitmapText would throw an error if you passed in a number as the text property to the constructor. It worked if you used the text accessor directly because it cast the value to a string, but the constructor missed out this step (thanks @lewispollard #2429)
