Stop all processes if one fails

[jwoertink]

No clue if this is a good idea or not, but I just ran in to an issue where I ran lucky dev, and then got all my web output and started browsing my app. I was trying to figure out why I was missing some data so I scroll back up my log to find out that my mosquito process never compiled. I had a syntax error in my worker (why the web still compiled, I have no clue...), but since the worker process never actually booted, then it seems like the web shouldn't have either. 🤷‍♂️
