This now follows the other template functions, and implicitly also
fixes that playbook handler includes were still processed by Jinja2.

Allow hosts not in inventory to override inventory with -i "host1,host2:port" etc, which is the original intent
of --override-hosts.

Do not run unit tests against the EVENTS code because it is subject to change and that does not mean anything is broken.
If we want to test playbooks, it's best to test the result of a playbook to make sure it does the correct thing.  Also
remove playbook2/3 yml which were not used.

Fix correct variable expansion in includes only_if.

There's not need to run the complete include through the templating engine.
Several variables were not included before the conditional was evaluated.

Support single handlers for notify.

Fix YAML hosts list.

Support list indexing in varReplace.

Fixup unicode varReplace templating.

Fix for bug #264

The original patches should have conflicted?
53bde0bf vs efde61e5

Added the network address of an interface as an ansible variable

Fix for issue 353

mktemp creates the temp directory 700 only.  If the sudo-user is not
root, the other user will not be able to run the command (Permission
denied error).  This adds the executable bit for all on the temp
directory.

Allow camelCase variables in varReplace.

Added parameter to the apt-get install command to prevent interactive conflict resolution

Fix hang on large command output.

override-hosts is gone since we can't load inventory for hosts (so it's not an whitelist), but we can
still support hosts outside of inventory if you pass in an array of hosts.  Ports are supported,
but not much other info.

Support nested variables in varReplace
