Use a single Vagrant base box since the one made by Box-Cutter supports both
VirtualBox and VMware (Workstation and Fusion) hypervisors.

Fix monit ZNC monitoring

The 'fuse-utils' package doesn't exist on Ubuntu 14.04 and is marked as a
transitional package on both Debian 7 and Ubuntu 12.04 that installs the
'fuse' package.

Since Debian 7 is the officially supported distribution we can safely
switch to install 'fuse' instead of 'fuse-utils' and we also gain
compatibility with Ubuntu 14.04.

This change set builds collectd from source and configures it in one of
the following ways:

- If Librato credentials are present, collectd will be configured to
send data points to Librato using the collectd-librato plugin.

- If no Librato credentials are present, collectd will be configured to
write RRD files locally (/opt/collectd/var/lib/collectd/rrd by default).

apache sites: Wrong ownership and filename

/etc/apache2/sites-available and old (dangling) symlinks in
/etc/apaches/sites-enabled.
Also, remove unnecessary apache2 restart after creating a new
virtualhost but not yet enabling it.

Add note about editing hosts file to README

* Postfix: Trusty comes with postgresql 9.3, not 9.1
* owncloud 6.0.1 is part of the distribution, doesn't require opensuse repository
* owncloud requires libapache2-mod-php5
* uses prosody repository that matches the ansible_distribution_release (trusty, wheezy, etc)

The virtual site files must be owned by root (serious security issue)
and they must have the .conf filename suffix for a2ensite on
Ubuntu 14.04LTS (apache 2.4.7).

I guess the .conf appendix is a change introduced in apache 2.4.
This change should make it backward compatible with apache 2.2.

On Ubuntu 14.04 LTS, a2ensite automatically appends ".conf" to the filename it looks for in /etc/apache2/sites-available/
Therefore, the file "/etc/apache2/sites-available/roundcube" must be renamed to
"/etc/apache2/sites-available/roundcube.conf".

Security issue:
This file must be owned by root, otherwise it is a huge security issue (User www-data could modify the file and get root at next restart of apache).
