ircbouncer: connect to default server (freenode) using ssl

Use gathered facts to determine the correct network interface in the OpenVPN role

OpenVPN role

Fix local tarsnap key path in readme

Turns out it should be in the tarsnap role, not common. :)

Added friendly_networks variable to denote whitelisted networks

Set permissions and owner on virtual mail domains

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)

Updated the OpenVPN role so certificate expiration is handled correctly

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)

Testing & CI

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

added SHA check for tarsnap

Ignore ufw error resulting from known bug on Debian 7

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

Closes #73.
