- Added Ansible modules since now the Apache role depends on the ca-store which needs the dhparams module.

- Move pre_tasks to a seperate play because run_once is currently not supported with the free strategy.

# Conflicts:
#	tests/playbook.yml

- Enable free Ansible strategy to allow each host to proceed as fast as it can to help speed up some plays.

- Don't install apache2, already covered by apache dependency.
- Removed support for Trusty, don't have cgit packaged.

- Caching the entire virtualenv in Travis CI has proven to cause issues, caching just pip's cache directory.

- Use privileged container instead of just adding the sys_admin capability (the latter has been shown to be cause unrelated issues).

# Conflicts:
#	README.rst
#	defaults/main.yml
#	handlers/main.yml
#	meta/main.yml
#	tasks/main.yml
#	vars/main.yml

- Use octal numbers for file permissions.

- Remove mention of tests/requirements.yml from the Requirements section in the README, relevant only for testing.
