Add contact alias #28
Description
Massive numbers are not convenient, even if they are safe.
Consider adding a optional contact alias when a contact address is added. This could be client side for example. The ability to rename the username of some added contact.
Additionally, allowance of a user to define their own alias would make for more intuitive contact address booking. However it would seem that adding your own personal alias on the client should not lead to excessive exposure. That is, the alias of a user should only be provided after some approval.
