Use openssl to verify the certificate

Using openssl is consistent with previous instructions and has the notable
virtue of being cross-platform.

Vagrant provisioning currently fails without irc_timezone set in
vars/testing.yml.  This is probably due to changes introduced in
al3x/sovereign#300 to permit the znc timezone to be configured.  The
file vars/users.yml already has a TODO entry for irc_timezone.

Use native Ansible modules in the OpenVPN role to seed the serial and database files

Fix privilege error in monit tomcat6 config

database files.

The tomcat6 user doesn't have the right privileges to run the
/etc/init.d/tomcat6 script.  Removing these lines allows monit to
restart tomcat if it stops for any reason, and makes the tomcat6 monit
config more consistent with other monit configs elsewhere.

Since 1.0, znc has allowed you to specify the user's timezone:
conveniently, in tzinfo format.  This allows the user to configure and
specify that timezone.

This matters because it affects the timestamps that znc issues when
playing back the buffer after a disconnection.

for more info see:
- http://wiki.znc.in/ChangeLog/1.0#Timezones
- http://wiki.znc.in/Configuration

There is also a zpush_timezone configuration option, which could at some
point be unified with irc_timezone into a common configuration item.

Add instructions for making crypt salted hashes using Python and passlib

Quotes removed around salts and hashes in existing examples because, AFAIK,
base64-encoded strings contain no characters which must be escaped in YAML (the
following are not in base64: '!', ':', '|', '>').

ZNC: don't make install if configure or make fail

ZNC module compilation can fail on memory-limited systems, causing ZNC
to not work properly. But even after the failure, make install still
creates /usr/local/bin/znc. Thus Ansible would skip the ZNC build and
install step on future runs, despite ZNC not being correctly installed,
causing the playbook to appear to complete successfully and requiring
manual troubleshooting.

Resolves #114

This commit moves the monitoring role to the bottom of site.yml so that
it is executed after all other roles.

This is needed because the monitoring role conditionally installs Monit
configuration file based on whether some other packages have been
installed or not (such as ZNC).

This patch also adds a comment to the "monitoring" entry within the
"roles" list and a `roles/monitoring/README.md` file telling users why
the monitoring role has to come last.

Remove WebTests.test_znc_http test since ZNC web interface isn't exposed to

(Tested only with Debian 7 VM from the Vagrantfile)

ZNC 1.4 uses a new section within the configuration file to specify
password hash and salt. This requires adding a new Ansible variable
'irc_password_salt'.

Also update the README file to reflect above changes.

Also makes code slightly terser.

Update the Vagrantfile so that it is possible (and easier) to spin up Debian
7, Ubuntu 12.04 and Ubuntu 14.04 VMs. Although Vagrant allows spinning up all
of them simultaneously, there may be conflicts assigning host names and IP
addresses.

This Vagrantfile also enables the vagrant-cachier plugin (if installed) to
cache downloaded packages across subsequent runs of the same VM.

Running "vagrant up" will bring up only the Debian VM since it is the
officially supported Linux distributions. Ubuntu 12.04 and Ubuntu 14.04 must
be started explicitly by running either "vagrant up precise" or "vagrant up
trusty".

Subsequent runs of wallabag's playbook result in the 'install' directory being
recreated, (after the "Clone wallabag" step) kicking wallabag's first time
setup procedure.

With this patch we automatically remove the 'install' directory if wallabag's
configuration file appears to be in place before cloning the repository.
