Users should be able to select languages they speak

[DragosPetria]

To ensure that everyone has a good experience and can communicate, we need to take languages into account when matching users.

Language should be country default (@Mokto or device? device is probably pretty bad), and users should be able to add and remove languages on the account settings page.

Matching algorithms should then only match people with overlapping language settings

As discussed on Slack, I think language should be "open" per default.
We're expats, but most people aren't.

Open by default, yes, but if you alter it, it should be taken into account?
