[PATCHES v3] GPO support for client machine policy
These patches add Group Policy support for client machines. Adds a
winbind event that calls samba_gpoupdate to apply local machine
policies. Adds the option "apply group policies" to smb.conf, which
determines whether group policy will be applied to the client.
To start off, we only have Environment Variable policies.
Fixes in this patch version:
* changed "winbind gpupdate" smb.conf option to "apply group policies".
* Checks for windows paths in the PATH variable, and ignores them.
* Also adds testing for the windows path ignore.
