set_owner_if_different and set_group_if_different seems to need path
expansion too

Path might have to be expanded on some operations. It seems that path
containing '~' are not.
Using os.path.expanduser in appropriate places solves the problem, but
this might be required in many other places.

Make all lookup plugins accept lists as arguments

Alphabetic inventory hostname patterns.

Allows whitespaces around assignment operators when defining group variables

fix documentation for authorized_key in advanced playbooks page in docsite

Allow parameterized playbook includes to define complex variables

To be used like:
- include: playbook.yml
  vars:
    mylistvar:
    - item1
    - item2

Lookup plugins should accept a string or a list, and always return
a list, even if it is just one item.

cleanup Example output in ansible-doc

when defining group variables

At the moment Ansible prefers yes/no for module booleans, however booleans in playbooks are still using True/False, rather than yes/no. This changes modifies boolean uses in playbooks (and man pages) to favor yes/no rather than True/False.

This change includes:

- Adaptation of documentation and examples to favor yes/no
- Modification to manpage output to favor yes/no (the docsite output already favors yes/no)

Ensure files created by authorized_key have correct selinux context

Three changes:
* Add set_default_selinux_context() to module_common that sets
  a file's context according to the defaults in the policy
* In atomic_replace(), set the default context for the file if
  selinux is enabled and the destination file does not exist.
* In authorized_key, set the default context when creating
  $HOME/.ssh and $HOME/.ssh/authorized_keys.  If these already
  exist, this won't touch them.

Subverion module improvements

I guess my previous pull request was confusing, by changing the message to something we already do for tasks, it makes it more clear.

Just like we say:

    TASK: [foo bar]
    skipping: [system01]

The message now is more clear:

    PLAY [wagawaga] *******************************
    skipping: no hosts matched

It makes it clear that we are skipping the play, just as is done for a task when a condition is not met.
