File module fix for symlink from relative source path

service enable=on/off

Instead of one per host per polling cycle.

It wasn't killing the job at all before.
Indentation was 3 spaces.

Introduce group_names in template variables.

This is a list of all the groups a host is in.

from modules remotely when they fail to parse, and this is VERY useful data.

treated -D as a way to show stderr, and make sure modules don't include things on stderr.
Update docs and test module script to come into line.

and various modules.

This reverts commit 6341a954.

Some tweaks to first_available_file mostly in terms of error handling and not trying src= to be present
as it is not used here.

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

first_if_available and yum fixes

add first_available_file look up to _execute_template and _execute_copy
to runner.

add this data to playbook handler so it can be included into module_vars

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`.

[devel] ansible-playbook hangs if not passed --extra-vars

ansible-playbook release-my-app.yml --extra-vars="version=123"

And make $version available in the playbook without re-editing the file

Return the octal mode of a file instead of decimal.

Service module crashes if args has no "=".
