Add an option to show display names of users

[balsoft]

Currently, weechat-matrix shows "nicks" (I don't know the proper name) of users in the chat. This can get rather unpleasantly confusing in e.g. bridged Telegram rooms:

It would be rather nice to have a configurable option to show display names instead.

At this point it's unlikely to be implemented in the script even though a PR has been available for quite some time here #28.

The Rust rewrite will support this.

Thank you for your work.
If you're working on a rust plugin, does that mean you're going to abandon the python plugin?

[poljar]

Once the rust plugin has feature parity the script will be abandoned, until then the script is in maintenance mode.

That's strange because on some rooms I see the display name, but on other no.

[poljar]

The script has some hacks and it'll use display names if there are no conflicts, but it's lacking any smart way to deal with the conflicts so it just uses the full user id if there are conflicts.

Ok, so maybe I got another issue? In rooms where there is definitively no conflicts, I still don't see the display names.

Here the user Amora does not conflict with anyone.

So the script will some times use display names but some times the local part of the full user id. So it seems to work as intended even though it's not pretty.

Ok so I gave a look to the code and their is only very few cases where the display name is actually used: https://github.com/poljar/weechat-matrix/blob/master/matrix/buffer.py#L1069.

Now I understand why I don't see display name (and I patched the script to show them everywhere).
