The stock rspamd package provided by Raspbian (jessie) is at version 0.6.10.  The rspamd repository doesn't offer binaries for the armhf architecture (e.g., Raspberry Pi 3) in order to get a more recent package.  Instead, use the yunohost repository for rspamd package (currently at 1.3.5) on armhf.

Enable ownCloud virtual host automatically

Bump selfoss_version

Fix mail_virtual_domains config reading in opendkim

without this change it fails on ansible(2.2.0.0) with the following message:

    TASK [mailserver : Generate OpenDKIM keys] *************************************
    fatal: [sovereign.host]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'unicode object' has no attribute 'name'\n\nThe error appears to have been in '/Users/nfedyashev/Projects/sovereign/roles/mailserver/tasks/opendkim.yml': line 19, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Generate OpenDKIM keys\n  ^ here\n"}

Fix bare variable depreciation

Newer versions of Ansible complain when using bare variables like
`mail_virtual_users` and prefer the newer `'{{ mail_virtual_users }}'`
syntax.

Noticed the depreciation warning with Ansible version 2.1.2.0.

The debian81 image used before is no longer available.

The directory `/decrypted/roundcube` is not writeable by the user
`www-data`.  This leads to "unable to connect to the database" errors
from roundcube on new installs.  This patch corrects the problem.
