1.8.4

- Improved autoCSS detection so that it ignores native x/y/width/height properties on DOM elements (which <img> elements have) and is faster.

- Fixed jquery.gsap.js plugin so that even if another "Ease" or "CSSPlugin" is defined in the global scope (like EaselJS or TweenJS does), it looks in the correct spot (avoiding errors)

- Fixed issue that could cause an element's scaleZ to be tweened if you define only a "scale" in the tween (rather than scaleX, scaleY, and/or scaleZ independently)

- Fixed issue that could cause a TweenMax's repeat to be ignored if you check its duration() before doing anything else (if the tween rendered once or you checked totalDuration() or almost anything else, it would be fine previously - just checking duration() right after instantiation could cause the issue, but it's fixed now)
