boxes (WIP).
- Removed docker function, replaces by specific sciprts.

- docker clean removes created but not run containers.

  command if specified, otherwise runs the docker executable as normal (kind of
like aliases in git).

- Don't set default Ansible vault file, Ansible doesn't ask for vault password even if --ask-vault-pass is specified.

- Added function for rudimentary Docker images and containers cleanup.

- Comment out privilege_escalation options in ansible.cfg, caused some wierd erros with Vagrant and Molecule.

- Updated Aspell dictionary.

.bashrc.

- Added a global GOPATH and alias.
