Create and store labels of devices

[bmann]

When linking a device, a device "label" of the new device should be generated. This might be as simple as browser fingerprinting, eg:

• Firefox Desktop Mac
• iPhone
• iPad
• Android Device
• Microsoft Edge Desktop Windows

And/or something as simple as Device 02, Device 03, etc.

On first link, don't make it editable. Should be underneath username. Can be edited after the fact in device / linking management.

Future:

• login to Auth, list / manage / rename devices

Keybase's device listing / linking can be reviewed for inspiration.

Problem right now is where to store this information without centralizing it in the database. We know the root DID of the user, but no other information is centralized. This might be something where the DID is the key to a JSON list of devices that is stored in IPFS by the Auth system? Needs more design work.
