[get_url module]parse content-disposition filename parameter even if it's not quoted

Name appears to be a required parameter for cron module

module docker - expose will fail to port forward network connections if there are spaces in the CSV value

now acl expands tildes

Hostname strategy implementation for OpenRC based systems (e.g. Gentoo)

The "name" parameter seems to be rather important as the identifying feature of a cron job.  This is an update to the documentation to further emphasize this.

As far as I can tell, `name` is a required parameter.  The guard test at (now) line 458 says you need name if `state == present` and at 464 if `state != present`, although that's not quite as clear.  Each of the code paths at 485 - 495 pass the name param through to `add_job`, `update_job` and `remove_job`, and the actual _update_job method earlier seems to require it too.  However I don't really know python so I may be wrong, but I can't see the circumstances when `name` is not required.

Make sure cmd is UTF8 encoded before splitting. Fixes regression introduced by 80df2135.

For content-disposition response header field, try to parse filename parameter even if it's not quoted.

Bugfix: #8720 winrm.py: protocol.send_message() crashes with https

Generate warnings when users are shelling out to commands
rather than using modules

Can be turned off on a per-action line with the documented
warn=False flag. Can be turned off globally using
command_warnings = False in ansible config file.

Print out warnings using the standard playbook callbacks.

Created some additional tests in TestRunner.test_command
and also a demonstration playbook.
