Tween's easing functions incorrect

[ratkingsminion]

I tried to compile an example (based on the old one) for the new Tween stuff, and noticed that at least the easeInOutBounce function just doesn't work correctly, the values are far off.

Also, the ease*Sine functions are basically just a wrapper for using Sine(), which means t goes from 0 to 0. This is is not how tween functions usually work. A real tween always should start at 0 and end at 1.
