Implement a simple way to contact other participants

[mariobehling]

1. Add a link "Participants & Chat" to the event side panel
2. Add a page with a list and search box of participants on the participants page. On this page also show an area "Chats" which should show an area with previous chats. (Take inspiration from Whatsapp).
3. When a participant clicks on a participants open an area on the right with basic participant info and two options
   a) Chat
   b) Video Call
4. When the user clicks "Chat" open a chat window and send the invited user a desktop notification. Also add the created chat on the area "Chat" on the page "Participants & Chat"
5. When the user clicks "Video Call" open a new tab with a personal Jitsi window. Show the invited user a desktop notification and add the info "Invited to Video Call" to the chat with the user. (Both parties should be able to click that link)
