Frontend

[chunkybanana]

Adds:

• functional status lights (and an alert websocket)
• a dialog for the mailing list which is broken because CORS
• Charts are no longer an antialiased lagfest
• Made johnson duplication bug much worse
• Fake websocket now works for testing purposes
• Alerts now show up properly and are displayed
• TLS (and a basic http[s] server)

Doesn't add:

• Diagnostic "server connected" messages (these are kinda hard with how things are structured)
• Making things work on big screens (todo at library on weekend)
