mail_virtual_xx list were not use correctly in tasks.

We got error 'unicode object' has no attribute 'name' because:
with_items:
 - "{{ mail_virtual_xx }}
is understood has a list of strings containing information extracted from {{ mail_virtual_xx }} variable

 Now we use:
   with_items: virtual_domain_xx}}"

Based on playbook from https://github.com/phred/5minbootstrap

These are the changes necessary to enable Roundcube's manage sieve plugin to mange server-side sieve filters.

OpenVPN role

Added friendly_networks variable to denote whitelisted networks

Move the settings of the virtual mail directories into a separate
ansible task.

Without the owner being set to vmail and dovecot, when a virtual user
tries to access their mail account, dovecot throws an error that it does
not have permission to create the mail folder for the user.

With the owner and permissions being set the user's mail directory is
created and they can successfully sign in.

Adds/subscribes Drafts, Sent, Junk, Trash and Archive mailboxes.

* Removed unicode char from task name (ansible 1.3 doesn’t like it)
* Use ansible sysctl module instead of lineinfile
* Wait for only 5 seconds (for fully automated deploy)

correctly. The number of days that a certificate will be considered
valid is now a user-controlled variable and is set to five years by
default. (Fixes Issue #87)

This URL works for all releases, not just the latest one.

 * Add an openvpn_server variable
 * Move ${openvpn_client}.{key,csr,crt} to
   ${openvpn_client}/client.{key,csr,crt}
 * Generate ${openvpn_client}/${openvpn_server}.ovpn config file
 * Copy over a self contained directory of file per client that can be
   imported by networkmanager in ubuntu or run directly with `sudo
   openvpn ${openvpn_server}.ovpn

because it's not available in a stable ansible release yet

In order to check the version of the linux distribution we need to
set `gather_facts` to True.

Closes #73.

(No more "Removing leading '/' from member names" warnings)

Scripts used to rotate tarsnap backups exit when a command fails
Cron will catch that return code is not zero and will send message to root

No more silent failure

  * OpenVPN setup is now fully automated. No configuration changes
    are necessary (though the defaults can easily be modified) and
    all manual command line steps have been eliminated.

  * Removed the dependency on easy-rsa in favor of pure OpenSSL and
    OpenVPN commands that are executed by Ansible

  * Improved the security of the OpenVPN configuration
    * Increased the default key size to 2048
    * RSA keys are only readable by root
    * The cipher and authentication digest are now configurable. If
      your client supports it, you can use AES-256-CBC and SHA256
      instead of BF-CBC (Blowfish) and SHA1 which are the defaults.
      Or you can be a really cool, paranoid, crypto hipster and
      use CAMELLIA-256-CBC and SHA512 with an RSA key size of 4096.
    * Enabled "HMAC firewall" functionality using the tls-auth option
      and automated the generation of the 'ta' key that it depends on
    * The OpenVPN daemon becomes an unprivileged user after it starts

  * Automated the retrieval of the files that clients will need in
    order to connect to OpenVPN

  * A pause prompt outputs basic configuration information after the
    role has finished running

  * Variables are referenced using the new Ansible variable format
    (e.g. {{ var }} instead of $var)

  * Added a flush_handlers command to the role that ensures OpenVPN
    will restart prior to dnsmasq (fixes issue #63)

  * Fixed two bugs that were preventing packet forwarding for IPv4
    from being enabled correctly

Instead of sending email to {{ admin_email }} we send them to root user.
These emails will be redirected to the appropriate user via
mail_virtual_aliases variables

Apticron is configured to send email to {{ admin_email }}

ignoreip field inside /etc/fail2ban/jail.local is populated with
server_ip_address variable

Add tasks to install script/tarsnap configuration file and a cronjob to run
the backup job
Number of hourly/daily/weekly/monthly backups kept can be configure from the
tarsnap.sh script

Thanks to this script, we don't use all the backups which save space on
tarsnap server and thus reduce the price to pay

Sovereign does not currently use jabber/xmpp or insecure smtp.

That way the default values will not be applied by mistake. The user
needs to uncomment the lines from `vars/users.yml` and set them.

Also renamed openvpn variables.
