New Keyframe Type: "Jitter"

While doing some animation work over the past few days, I found that
it would be useful to be able to tag keyframes as a another type yet:
"jitter" for fill-in secondary motion (i.e. blinks/hand-keyed camera
shake). Of course, what you really use these for is up to you, but
this is one more option when you need it :)
