[Feature request] Mute a group chat

[Hexcles]

Glad to see group chats are working well, great work! Yet I notice that there seems to be no way to mute a group chat as in the mobile app. Even if I click on "leave the chatroom" (I'm using Empathy FWIW), the group chat will automatically pop up once there's new message.

It would be good if we can somehow "mute" a group chat (and of course, without losing the group chat forever). Furthermore, it would be awesome if that "muting" settings could be synchronised automatically from the official app (not sure if the data is available in the API though).

This is a very reasonable request, but it stands on two points:

1. We need a connection Interface with API for message notification. Something like "Enable notification", "Disable notification" and may be "Notify on (nickname) mentioned".
2. We need a way to get messages for muted channel.

I think on it and will add a comment later.
