This serves the web-dev surface iFrame from another domain, such that user-created levels can't sniff cookies from a visitor to their page. It forces a redirect if a path is accesses through the wrong domain.
Use ENV variables for hostnames
Allow messages from all relevant domains
Use the right iFrame URL for different domains
Let the load balancer check /healthcheck
Add special handling for china server
Generalize subdomain handling
This heavily refactors SpellView and adds infrastructure for receiving and reporting Errors raised by the web-dev iFrame. The web-dev error system, the Aether error system, and the Ace html-worker avoid disturbing each others' errors/annotations (though currently Aether+web-dev errors won't coexist), and they clear/update their own asynchronously.

Show stale web-dev errors differently
Some web-dev errors are generated by "stale" code — code that's still running in the iFrame but doesn't have the player's recent changes.
This shows those errors differently than if they weren't "stale", and suggests they re-run their code.
