Updating GSAP to 1.11.4

- Fixed issue that could prevent transforms from working in Opera if force3D was set to true (regression in 1.11.3)

- Worked around a browser bug affecting Draggable that could cause bounds to be imposed incorrectly (making the target element jump) in a particular scenario.

- Fixed an issue in ScrollToPlugin that could cause a tween to get killed when the maximum scroll value was reached (only if the destination value exceeded the maximum scroll amount).

- Updated KineticPlugin to work with KineticJS 5.0.0 (which means it is not compatible with earlier versions, since KineticJS introduced significant API changes in 5.0.0)

- Worked around Firefox bug that could prevent borderWidth from animating (only if it wasn't defined inline on the element)

- Updated copyright dates
