Ansible support configuration in:
```
~/.ansible.cfg
/etc/ansible/ansible.cfg
```
this patch add current user (usefull where user have some different projects) with the oreder:
```
./ansible.cfg
~/.ansible.cfg
/etc/ansible/ansible.cfg
```
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.
If I create a database from scratch and assign permissions by doing:
- name: ensure database is created
action: postgresql_db db=$dbname
- name: ensure django user has access
action: postgresql_user db=$dbname user=$dbuser priv=ALL password=$dbpassword
Then it fails with the error:

This fix fixes the problem by not executing the regex if the
db query on pg_database returns None.
When using template module, if a restrictive umask is set, the
sudo_user won't be able to read the /tmp/ansible-dir/source file
after it is copied across following _transfer_str
I wonder if this behaviour shouldn't be abstracted somehow (as
this correction also happens after put_file in the copy module too)
