Actor model with Web workers

PROs:

• might be a better fit than custom events,
• and it's still native to the web platform,
• no framework/dependency rule compliant,
• it's just gonna need a micro lib,
• plus it will remove much of the load from the UI thread,
• and this app has a lot of parts that need to do continuous complex calculations, which have no place on the UI thread,

CONs:

• shotgun refactor
