Standardize format

The files in FWCore/Utilities that handle ROOT6 dictionaries were all extensively modified a while back by Paul Russo.  I now need to make changes to them, so I am converting the files back to my coding style to preserve my sanity.
The only changes are:
1) Reformatting white space and indentation.
2) putting the const qualifiers after the type, rather than before
3) Removing one "using namespace std" and adding std:: where needed.
This is only being done in FWCore/Utilities/*/*Dict*
These changes have been tested.
