Chat, video & audio-conferencing using WebRTC

- 💬 Chat integration! Nextcloud Talk comes with a simple text chat. Allowing
you to share files from your Nextcloud and mentioning other participants.
- 👥 Private, group, public and password protected calls! Just invite somebody,
a whole group or send a public link to invite to a call.
- 💻 Screen sharing! Share your screen with participants of your call. You just
need to use Firefox version 52 (or newer), latest Edge or Chrome 49 (or
newer) with this Chrome extension.
- 🚀 Integration with other Nextcloud apps like Files, Contacts and Deck. More
to come.

And in the works for the coming versions:
- ✋ Federated calls, to call people on other Nextclouds
