Force output panel on when python errors

[JohnEdChristensen]

User's might not notice when an error is hit in their sketch if the output panel is not opened. Open it whe errors are hit. See here:

diver/src/index.js

Lines 44 to 50 in 2328337

	//update the output panel when code is run
	diverVisual.addEventListener('pythonError', e => {
	//@ts-ignore low priority
	addToOutput("There was a python error:\n" + e.detail, "error")
	//TODO force output panel on
	});
