Add a `recursive` option to the git command.

Make it possible to clone without submodules by setting
recursive to no. Default is yes, so no change is needed
in existing plays.
Expose the playbook to callback plugins
add registry option to npm module
Started the development of the 'chdir' functionality for file module - creation symlinks without the base directory prefix
Found a way how to have symlinks towards files without absolute paths in prefixes; fixed incorrect force setting on the hard links, which can not point to non-existing files
Updated the force parameter description; added one example how to create the symlinks pointing to non-absolute paths

- Explain which properties are managed when manage_dir is True.
Improvements to the rax inventory script
Treat 255 errors from raw as dark host

Any other module is able to detect a dark host, but raw was treating 255
as a return code from the module execution, rather from the connection
attempt. This change allows 255 to be treated as a connection failure
when using the raw module.
Added template call to _executor_internal to allow the passing of arbitrary data to modules.
Did my best to rebase. Now includes the latest changes made to devel, along with my change of adding category option to module
