Contact renaming

[totikom]

The Problem

In messengers based on phone numbers like Telegram, Signal, WhatsApp users can assign names to their contacts. It allows to use easy and understandable aliases (like "Mom" instead of the full name of your mother).
More over, Matrix promotes itself as a secure way of communication, and therefore using random strings as nicknames can be common (as a countermeasure against OSINT). It is hard to remember, which of random strings is your friend's nick, but it will become trivial, if you can locally change his/her nickname to real name or smth else memorable.

Proposed solution

Add a way to locally (only in one session) assign names to your contacts.

Alternative solutions

This information can be synced across different sessions, but it will require additions to the Matrix Protocol, which sounds like an overkill.

This is at least related (if not a duplicate) of #1908.

Also the spec change would probably be this one https://github.com/matrix-org/matrix-doc/issues/690.

Yes, matrix-org/matrix-spec-proposals#1908 sounds quite close.
I think my issue can be closed.

You can do this yourself so the devs don't need to spend time doing it :)
