(Using varReplace function originally from yum, thanks Seth)

Playbook test upgrades, made some notes about callbacks we need to add.  Still need to compare events
recieved vs expected so we can be notified if this test breaks, and also to add some more detailed
playbooks that use includes & async, etc.

Import cleanup, plus have /bin/ansible remind you if no hosts were matched by a pattern (for instance, assume
there was a typo in the pattern)

Remove "import *" from bin/ansible so we can use pyflakes, and remove unneeded imports in the process

Add the failtest module, primarily for easy development testing purposes.  RPMs/etc need not ship this.

Fixup the code that allows facter/ohai/other data to bubble up and be used in future action lines.  It's a niche
case compared to usage in templates but it should work and will be wanted later for conditional support.

Inside of runner, do not 'import *' from utils, so we can more easily tell where functions come from

Preserve changed data on file and template ops when the mode operations don't result in a change but the files
were still replaced.

works in Ansible in general.

If the inventory file is EXECUTABLE, treat it as a file returning JSON, if called directly, return the host
and groups list.  If called with an argument of a host name, return the key=value data for that particular
host.

note some changed=True/False detection bits in file module still need tweaking

Because folks on RHEL 6 (not CentOS 6) have some issues with asciidoc, do not build the asciidoc from
the rpm or make install targets.  Also modify the make install (only) to copy over files into the library
directory since the setup.py does not do this (due to a distutils bug, more or less).

Add basic test of yum module (VERY basic) just to make sure syntax remains ok.  Need to do something
trivial for service and git module also.
