Adds ability to check service status based on pattern.  The pattern
is a simple string.  If a pattern is provided, the output of ps is
checked first.

Make pep8 tests run against the library directory as well, and associated tweaks (mostly to indentation) in the library
directory.

whitespace + remove deprecated YAML parser (migration script lives in examples/scripts and warning was added
in 0.6 release)

Add encoding lines to python modules such that they can take unicode options if they are fed them, since the
AnsibleModule stuff no longer base64 encodes for simplicity and speed reasons.

If _do_enable() is run and returns rc == 0, set changed=True
Add enabled and state to result if they are supplied when the module is
run.

Allow use of service module with just enable parameter, per issue #755.
Also fixed two other issues:
- fixed parameter to be 'enabled' per docs, not 'enable'.
- fixed if block that checks whether to run _do_enable() to check
  whether the parameter is set, not the value of the enable value which
  may be None or False.  If enabled=no, the service would never be
  disabled.

The service module was printing stuff to stderr, returning two
JSON dicts, not using consistent 'failed' values, had dead code
and unused variables.  Added detection for the case when service
status returns 'xxx is dead and pid file exists' and made the
code a bit easier to read.

- Added Upstart support
- Added an initial unknown state
- Prevented state changes when the current state is not recognized
- Changed the keyword recognition to a safer method

The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked.  I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
    shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.

running and to report errors from starting them

_find_binaries now sets the right globals
Binaries are now properly populated (reverse path/binary for loops)

Checks if update-rc.d (Ubuntu) or chkconfig (RHEL) should be used.
Adds basic bin path search for those binaries
Adds 'enable' and 'disable' options for 'enable' command since it's the
arguments that update-rc.d uses (this might be somewhat confusing to
have a command line with 'enable=enable', but probably mkes sense for
Ubuntu users).
Allows use of mixed case for 'list' and 'state' commands.

make it useful from /usr/bin/ansible and the API.  Also some minor style fixes.

When running the service module via sudo, `$PATH` didn't contain `/sbin`,
so the service binary couldn't be found.  This just runs `/sbin/service`
directly.  Output is spewed to stderr on error.

Added `list=status` to include the output of `service <cmd> status`.

all modules take a common parameter name.  But more or less we still work idempotently
in modules.

module vs command module for restarting.  May be some bugs and requires the service to implement 'status' -- and probably some better error handling (i.e. return JSON with "failed" element if failed).

Improvements welcome.
