* module.fail_json *must* have msg argument
Using http://github.com/ rather than git://github.com/ as it gets through more
firewalls

as it is /bin/false on many systems but /usr/bin/false on OS X
test/playbook1.yml now just does command true, rather than command /bin/true,
again so that it works on OS X

Changed from using which false to just using command false to
make it simpler and also match how playbook1.yml works

Setup module no longer saves to disk, as templates are mostly useful in playbooks and this allows lots of simplifications
around file pathing and removes occasional permissions conflicts depending on how things are used.

This adds a module that concatenates (ie. assembles) a file from
fragments in a directory in alphabetical order.  It chains the file
module afterward to fix up ownership and permission.  This also adds
tests for the assemble module with fragments in assemble.d.

If the module result contains "ansible_facts", that will be added to the setup
cache.

Don't force down ansible facts back to setup, the setup module won't like parsing them on input and that
data is already there.

The fetch module really should preserve the whole directory structure being fetched to allow subsequent calls,
particularly in playbook, to recreate the host tree structure.  Making it thus.

Also account for path difference in sleep in different distributions.

Some minor code shortening.  Added a test to TestRunner.

that commands now trigger change events.

Run tests in verbose mode.

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.

Fix async to use the new argfiles method (wrapping brain around rock, really must write module development guide)
