Wagtail 0.5
Merge pull request #8 from kaedroho/cleanup

Cleanup
add OpenCV dependencies
don't install libyaml - we've never used it for wagtail
version-bump stuff in common-requirements
Version bump elasticsearch
version bump box name to 0.3
need -y option when installing opencv
version bump to 0.3 in documentation
Cleaned up pgsql configs

- Removed locale gen code (postgres creating databases in UTF8 doesn't seem to be a problem)
- Removed pg_hba.conf (creating a superuser called "vagrant" allows the
  user to create databases without needing to use the postgres user, so
  this config is no longer needed)
Use new Vagrantfile format

Plus, vagrant automatically mounts current directory to /vagrant
Restructure

Make it easier to tell what each file does. Also, removes confusion over
the difference between build.sh and install.sh.
Removed unused file
Cleaned up APT package installation
Removed checks before installing things

These were added to keep the script from attempting to reinstall stuff
on every vagrant provision.

As this script is only ever run once, these are not needed and I think
the code looks much clearer without them.
Cleaned up virtualenv code

- Removed virtualenvwrapper (not really needed, no Python 3 support)
- Updated bashrc to be based on the one in Ubuntu 14.04
- Create a virtual environment in /home/vagrant/venv
- Use /vagrant as project directory (as this is automatically mounted by
  vagrant)
Upgrade to Elasticsearch 1.3.4
