Allow transport on tasks, and use it for local_action

Atomic copy2

Make get_url module always return dest. 

add logrotate config

The url_get module now includes the destination in the returned JSON.

The check for the destination being a directory is now done before
checking if the file exists, that way the user is informed that the
thirsty argument is required.

Made $groups and $group_names variables accessible in with_items

Support import of playbooks in other directories

Add support for ./ansible.cfg file

Fix inventory.get_hosts when hosts is a list.

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
```

Also modified code that feeds the groups data structure to templates so
that it resolves groups inside of groups to hostnames.

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.

Fix postgresql_user bug

Fix regex that allows passwords to get into syslog, use journal if available.

Have ansible respect private_key_file option

add import sys to virt module b/c it needs it if the libvirt python

Install action_plugins

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:

  File "/tmp/ansible-1347048449.32-29998829936529/postgresql_user", line 565, in <module>
    main()

    r = re.search('%s=(C?T?c?)/[a-z]+\,?' % user, datacl)
  File "/usr/lib/python2.7/re.py", line 142, in search
    return _compile(pattern, flags).search(string)
TypeError: expected string or buffer

This fix fixes the problem by not executing the regex if the
db query on pg_database returns None.

module is missing

The ansible command-line tool was ignoring the private_key_file option.

The config file incorrectly mentions the --private-key-file flag.
Should be --private-key
