fixup! Adding the MISSING Animation constructor to accept duration in milli seconds

Inserted the code for Animation constructor which accept integer value for duration in milli seconds.
Example, _animation = new Animation(10000); will create Animation object with duration of 1000 ms (1s).
We can still use _animation = new Animation(1.0f); to create the same.
We can also use _animation.DurationMillSecs = 10000; // 10 ms

Also the Animation parameter pascal case change is handled in the animation class enums
Added looping property and Stop(Animation.EndAction action) also,
