Initial deviceInfo implementation

[gmaclennan]

Description

This is a subtask of Add device info records #182.

As per #240, we want a user to be able to set a device name at a device level (e.g. for all projects), but the data also needs to be stored in each individual project (so that other clients can read it).

We initially only want a device to only be able to write its own device name/info, and for that information to be shared across all projects. In the future we might want to allow administrators to name devices, and for a device to have different names on different projects.

Tasks for initial implementation

• Add a deviceInfo internal dataType
• Add client.setDeviceInfo() and client.getDeviceInfo() methods
• Create a client SQLite table for persisting local device info.

Tasks for full implementation (tied to project.$member work)

• Implement project.$member.update() but only allow a device to update it's own deviceInfo (the role that is set by this method has different permissions, so needs to be evaluated separately)
• From MapeoManager, call project.$member.update() with the current device name when joining a project
• From the client.setDeviceInfo() method, call project.$member.update() for all current projects on the device
