Added

• Sprite: add support for aseprite texture atlas (including animation)
• Atlas: createSpritefromAnim parameter is now optional, and if not defined will use all defined index in the corresponding atlas
• Loader: new setOptions method that allows specifying custom settings to be applied to fetch requests (crossOrigin, withCredentials, etc..)

Changed

• Loader: loader settings such as crossOrigin and withCredentials are now deprecated and have to be set through the setOptions method

Fixed

• Doc: fix hyperlinks to source code within documentation (thanks @Waltibaba)
• Loader: fix settings for the fetch request not being applied in ES6 builds (thanks @B0sh)
