git module documentation: removed incorrect use of term 'remote branch' ...

Added additional template variables

Added two additional template variables
* template_fullpath - absolute path to the template
* template_run_date - date that the template was rendered
Documented these additional variables in the module documentation

Throw an appropriate error for it.

This is the name of the setting on the play level, and the options.
Should be consistent.

Update path_dwim() to return absolute path

If path_dwim() is provided a relative path to a file, it will now return an
absolute path of the playbook directory + the relative file path.

Make script module use raw module so it does not require python

[docsite] Added LEMP selected playbook

Add return code and error output to raw module

Since we use 'raw' heavily on equipment where 'command' and 'shell' are not (yet) working (and python may need to be installed first using raw) these improvements are necessary in order to write more complex scripts (with return code handling and separated stdout/stderr).

This change includes the following changes:

 - exec_command() now returns the return code of the command
 - _low_level_exec_command() now returns a dict, including 'rc', 'stdout' and 'stderr'
 - all users of the above interfaces have been improved to make use of the above changes
 - all connection plugins have been modified to return rc and stderr
 - fix the newline problem (stdout and stderr would have excess newlines)

In a future commit I intend to add assertions or error handling code to verify the return code in those places where it wasn't done. Since only the output was available, the return code was ignored, even though we expect them to be 0.
