Use `errs` for Error creation and hoisting

[indexzero]

I think this would solve a lot of problems in jitsu.showError

Can someone elaborate on this ticket? We need additional information for someone to start working on this.

[gradus]

Yes. Please elaborate and I would be happy to help address this issue.

I think I now see some of the issues with jitsu.showError and where error handling is lacking.

Going to try and start catching and tagging certain errors before they hit this handler. Hopefully we can remove the majority fo the code in jitsu.showError soon.

What exactly are the issue you are seeing with jitsu.showError ?

[jfhbrook]

The issue wish jitsu.showError is that it's a multi-hundred line error handling function. See: #321

I consider this issue (we have an errs library but aren't using it) to be a separate, and more minor issue.
