- SLES 11/12 Spacewalk/SUSE Manager

- Change to add SLES 11/12 Systems to site Spacewalk/SUSE Manager
- remove wget in favour of curl (part of minimal installations on rhel/sles)
the default is to have spacewalk installed with ssl support, I'm not sure if one deselect the option, in any case I'd always default to https

I can't speak for satellite 5 or suse manager.
