Enable IMAP virtual mailboxes.

Using dovecot's 'virtual' plugin, cf.

  http://wiki2.dovecot.org/Plugins/Virtual

The 'virtual/' namespace is visible in the NAMESPACE command
(hidden=no), but not in LIST (list=no). This should ensure that the
namespace isn't automatically synced by offlineimap, but nevertheless
visible by roundcube, cf.
