raw_params checking. Check NoneType for 'raw_params' before
proceeding.

While including var files using _raw_params adds additional new line
character, which makes Ansible to fail to include that file in.

include_vars will now also return a key 'ansible_included_var_files'
which contains the list of files that were successfully loaded.
This is useful information and, amongst other things, a way for users
to know exactly what files were included when debugging their
playbooks.
This also allows us to improve the integration tests around
include_vars.
