Multi device support

Need way better multi device support

Ideas:

• QR code, which we did have but I removed because it was large dependencies and a PITA to integrate with.

• Save to google wallet/apple wallet

With a QR code, you could "login" to another device:

• transfer semaphore ID
• split the user message limit bounds between devices
• This can happen using the users cryptokeys to encrypt and transfer the credentials/settings to another device through the servers websocket connection
