* 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"
