Add Win Robocopy module (#1078)
* Added more robust error handling * Add Win Synchronize module Renamed win_synchronize to win_robocopy Updating email address Adding "flags" argument. Adding a "flags" argument that will allow the user to pass args directly to robocopy. If "flags" is set, recurse and purge will be ignored. Add return code to output Added bits to support check mode Fixing typo in Documentation Updated Documentation to have "RETURNED" field Updated win_robocopy.py to have the RETURNED field. I also noticed that win_robocopy.ps1 wasn't really using the "changed" attribute, so I went in and made sure it was being set appropriately. Forcing bool type for recurse and purge flag Updated "version_added"

notes:
|

- This is not a complete port of the "synchronize" module. Unlike the "synchronize" module this only performs the sync/copy on the remote machine, not from the master to the remote machine.
|
||||
- This module does not currently support all Robocopy flags.
|
||||
- Works on Windows 7, Windows 8, Windows Server 2k8, and Windows Server 2k12
