Some editorial changes to antsRegistration observer files

I changed the full scale CC similarity metric's radius to 4 to be
consistent in all observers.

Add a new baseline for "antsRegistrationTest_SimilarityRotationNoMasks"

The "antsRegistrationTest_SimilarityRotationNoMasks" test was reporting
failure to dashboard. After inspecting the results and look throug some
code changes, I decided to replace the baseline of this test.
Also, I made some minor editorial changes to other files.
