s4:domainlevel - further improvements

Browse Source 
- The tool displays now also mixed/interim domain levels and warns about them
  (s4 isn't capable to run on them)
- But it allows now also to raise/step-up from them
- It displays now also levels higher than 2008 R2 (altough we don't support them
  yet) but to be able to get a correct output
