Refactoring `SketchException` to be available outside of `app` by joshgiesbrecht · Pull Request #1196 · processing/processing4

I think we're good to go now. I wrote a new, very tiny processing.app.SketchException that extends the utils one, so not only does it allow other modes to work but it still plays nicely when testing if something is a processing.utils.SketchException.

Once this is released, I'll submit changes to the other modes so they refer directly to the utils class, and when those are released then I'll come back and delete the extra file. Hopefully. Fingers crossed. 😆
