Update phaser.d.ts

Updated from last week

Also I think #843 is solved and supports this for example. I do not really see a problem with Casting as I do it fairly frequently. 

`var filter: Phaser.Filter.Marble = new Phaser.Filter.Marble(this.game, 800, 600, 4, 1);`
`var filter: Phaser.Filter.Marble = <Phaser.Filter.Marble>this.game.add.filter("Marble", 800, 600, 4, 1);`
`var filter: Phaser.Filter = this.game.add.filter("Marble", 800, 600, 4, 1);` <-- looses intellisense
