Create custom block workarounds for unsupported Scratch blocks

[djdolphin]

I doubt some of the less useful Scratch blocks like when () > () will be added to Snap!.

Would be this be the reason griffpatch's articulated lorry driving doesn't work, or would that be a seperate issue?

It claims it works, but once it opens in snap, the greenflag basically does nothing.

That might be the problem. Snap! also handles some features in slightly different ways than Scratch, and that can also break large projects.
