Sketches have a setOpacity method. There is now an opacity test in the animation tests page. There is an unfinished rotation function that is commented out in the sketch widget.
Sketches can now include a wedge object type. A wedge takes a position, length, width, and angle. Wedges have been added to some of the sketches in the animation tests.

Review
cleanup old copy paste
Added a setColor method to sketches, and a test for it. The method only changes the color of the stroke, not the fill (which only applies to wedges right now).
setOpacity method on labels

You can show/hide labels just like sketches now.  Used on brain example.
turned on highlight events for hotspots
Added test for clickable sketches.

Fill property on sketch config, update to lite method on imageviewer

* fill property on shape objects, althought it should probably move down to individual data
this allows objects to be clicked on in the center, but I haven't quite worked out the individual object classing and unclassing to allow hotspots to show properly
* imageviewer now updates the image to match the lit carousel, instead of calling a non-existant lite function for captioned images. we need to discuss the split between highlighting and selection on carousels.
