Support offset in publishable search restults
Fix unit tests.

The glossary entities were removed from production and will be added
back soon.  Having zero glossary entries broke some unit tests.  They
have bee temporarily commented out.
Merge branch 'master' into offset
Cleaned up unit tests.

The unit tests are too data dependent.  They need to be re-written at
some point.
Added orderBy parameter
Specific result counts shouldn't be used in tests.
Merge pull request #3 from imsweb/offset
