support for visitor mode in prosody, with some fixes for jicofo as well

Currently if you use the default `source` command in linux and the default `.env` file as declared in the `env.example`, it will fail because of the space in the string.

Using double-quotes around the string will solve this issue.

This makes it easy to re-attempt a botched build.
