PluginLoader._get_paths, as of 391fb98e, was only finding plug-ins that
were in a subdirectory of one of the basedirs (i.e. in a category
directory).  For example, action_plugins/foo.py would never be loaded,
but action_plugins/bar/foo.py would work.

This makes it so that "uncategorized" plug-ins in the top level of a
directory such as action_plugins will be loaded, though plug-ins in a
"category" subdirectory will still be preferred.  For example,
action_plugins/bar/foo.py would be preferred over action_plugins/foo.py.

The copy action accepts force=no, which tells it not to replace an
existing file even if it differs from the source.  The copy action
plug-in wasn't respecting this option when operated in check mode, so it
would report that changes are necessary in check mode even though copy
would make no changes when run normally.

Runner._remote_md5 was changed to make the logic for setting rc perhaps
a little more clear, and to make sure that rc=0 when the file does not
exist.

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.

A little more unit testing.

Added the backrefs parameter to the lineinfile module.
Added tests for the backrefs functionality of the lineinfile module.

Tests used heavily mocked version of the apt_key code, which meant that
it didn't properly test real life scenario.

Pretty straightforward.  Give it a URL with an exported GPG key for signing an
Apt repository.  It downloads it and will install it using apt-key.  It's even
smart enough to tell if it's already there (i.e. actually tells you if it
changed or not).

Use previous proven multiprocessing logic as the simplification didn't have the same Ctrl-C handling and may
be subject to race issues, though still don't pass Runner to each.  Still seems performant.

Various performance streamlining and making the file features usable in all modules without daisy chaining.

implement lookup plugins for arbitrary enumeration over arbitrary things.   See the mailing list for some cool examples.

pipes.quote is a bit overzealous for what we want to do, quoting ;
and other characters that you most likely want to use in your shell
invocations. The regexp is the best I could come up with to be able
to only replace the parts of the arguments that shouldn't be
executed.

    changed = True when changing symlink referent, #1008. Needed for tests.

date still issues warning and ignores TZ

- Updated tests to work inside bsd jails (127 addresses are an issue)

Remove tests that involve network effects -- makes things faster and they are not really deep tests here either way.

* 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.
