skip bucket

[timmatron]

I know this one is really far out there, but wouldn't it be great to manually cancel a particular bucket when rendering and move to the next. This would be especially handy on very reflective materials where you don't need it fully rendered, but would like to keep the rendering going.

Anyways, I'm just waiting for my stainless steel to render right now and I have time to think of little things like this.
