define color space for contacts about qabel-core HOT 2 OPEN

The color space should be defined in the core and used in both clients.

from qabel-core.

What about actually storing the color in the contact?
We need it in increasingly more places (the avatar in the new chat ui is colored for example) and that would open the implementation for extensions like a color picker. ...an extension method to Contact could be an intermediate solution... Contact.color that resolves to an enum with the color codes defined above. We could then fallback to a random (or deterministic alias-based) pick from this enum and later switch that implementation to something that changes an actual property of that contact IF we need it ^^

edit: new title proposal define color space for contacts
