Block navigation from the editor when there are unsaved changes

[davidqnz]

I'm not sure how to do this with react-router. If all else fails I guess the editor could be split off into a separate document and we could use window.onbeforeunload to pop up the native confirmation box.

for the conditional prevention of navigation react-router 5 has <Prompt />

though I've heard this is deprecated for react router 6

That issue thread was really useful! I had to downgrade react-router-dom to v6.3.x from v6.4.x to use the implementations shared in that thread, but they seem to work well. I will have to make some UX decisions now.
