Tint screen doesn't change in canvas mode.

[Hudell]

$gameScreen.startTint

This method doesn't work when the game is being run in canvas mode.

New to Git but I believe this will correct the issue if applied in rpg_core.

ToneSprite.prototype = Object.create(PIXI.Container.prototype);
ToneSprite.prototype.constructor = ToneSprite;

ToneSprite.prototype.initialize = function() {
     PIXI.Container.call(this);
     this.clear();
 };
