Decided to not deprecate legacy template syntax for now.  Backwards compat is important, though the docs will suggest the new way.

Some continued work on new-style templates and associated test code changes.  Legacy template functions
are marked with "legacy_" for possible future removal.

allow references to names of variables in with_items without needing to surround them with Jinja2 '{{' delimeters

Technically this isn't quite valid YAML when this happens, so we make it valid.  This means that if a future commander
API allows save/load it should make sure it does similar processing.

Add code to flag legacy templating like $foo.{bar} as deprecated in favor of Jinja2 {{ foo.bar }} so we
can remove the legacy system at a later date.

Allow jinja2 evals that produce lists to be used in with_items.  Ideally want something a bit less heavy
than the eval here.

compensate.

evaluate and replace '$item' with ''.  Really it doesn't make sense to include multiple playbooks
via a loop variable, as you can do this with task + with_items already (and it's a simpler code
path).  Given this is undocumented, this removes that feature, and we'll consider next how to
also add 'with_items' support directly to roles.

Don't set the item variable as eager template replacement will over-replace the variable as an empty string.

Test case and fix for shlex.split unicode bug

Enable virt module to work with different libvirt connection uris.

When operating on a unicode string in python 2.6, shlex.split returns
a result that does not work with the file constructor.

To reproduce this requires a task include that is templated (this is
because the templated string is a unicode result, whereas a non-
templated string is a non-unicode string)

The proposed fix (coercing the include parameters to string before the
shlex.split) may not be ideal but it does fix the bug for my test case.

When playbooks fail, attempt to create an inventory file in the inventory directory that allows rerunning
of the playbook against only the hosts that failed.
