Added new ServicesProposal library

- needed for bnc#887688
- Yast Network will have to set it (sshd)
- Yast Services Manager will have to read it and export it within its own configuration
- The test passes
- The package builds
It's a new file, year 2002 is wrong here, simply `(c) 2014 Novell, Inc.` is OK.

BTW should we use `SUSE LLC` instead of `Novell, Inc.`?
