- added terse syntax to modules.rst
 - added description of special variables to template module

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.

  plus a small fix in rst.j2 template
  manpages generated & checked
  modules.html generated & checked

backup=False is default

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.

Although library/copy can be corrected to understand that dest is
a directory, I can't see how to let _execute_copy know this and let the
file module know.

As a better solution than before #733, the copy module now explicitly (rather
than silently) fails when dest is a directory.

Could have used shutil.copy rather than shutil.copyfile, but this
implementation preserves the md5 comparison to avoid unnecessary copies

This reverts commit 865796c3687cc06920ddf29890de991287dc50f6.

(Superseeded by next commit)

Tested with OS X local connection and Linux remote. The paths to the
md5sum and md5 commands are hardcoded to the most common location. This
will definitely fail if the commands are elsewhere, or if the md5
command doesn't support the -q 'quiet' option.

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.

Call os.path.expanduser in modules so things work as expected even when using ./hacking/test-module script

Check md5sum before overwriting a file. Unconditionally copying changes the timestamp.
