Support import of playbooks in other directories

Browse source 
Previously, importing a playbook in a different directory didn't
work because all of the relative paths were resolved relative to
the top-level playbook.

This patch resolves relative paths on a per-play level instead of
relative to the directory of the top-level playbook.

Also removes the dirname argument from the Play._get_vars method
since this argument wasn't used in the metho dbody.
