Improve communication process after guest gets accepted

[timokoenig]

Current Implementation:
After a host accepts a guest to their place, both receive an email with the following information:

• Full Name
• Address
• Email / Phone number
• Hosts and Guests languages
• An info text to contact each other and to arrange the arrival

Improvement Ideas

• The email should be available in English and the first language of the guest
• The host can enter arrival instructions for each place
• Should we offer an InApp chat functionality? (Emails are so old school)

I think a chat functionality between host and guests would be amazing to exchange quickly.
In addition I think having a video chat before the entire address is provided would also be a nice to have :)

Done; implemented a chat with automatic translation of all messages
