I've changed a little bit the FEffects Tween class so you can use now, the short syntax that allows working directly on an object's property and you can set the easing function in the constructor.
Some new methods like : pause(), resume(), seek( n : Int ) and reverse() are added, and the following getters : position, duration, isPlaying and reversed.
The main loop function is inlined now too.
