Update SPARQL Documentation

[JasmineDW]

SPARQL query URLs need to be updated. This issue will track individual tasks contributing to this update

• [x] Update query to include Yasgui url, and Fuseki endpoint
• [ ] Alliyya to push modifications to live site
• [x] Clean up graphs
• [ ] Modify queries/documentation to reflect graph updates
• [ ] Update references to Orlando

[alliyya]

Will be retiring the following graphs that will affect current query pages:

• [x] http://sparql.cwrc.ca/data/orlando_volumes
• [x] http://sparql.cwrc.ca/data/orlando_volumes/1
• [x] http://sparql.cwrc.ca/data/orlando_volumes/2
• [x] http://sparql.cwrc.ca/db/BiographyV6

These should be replaced with http://sparql.cwrc.ca/data/orlando or http://sparql.cwrc.ca/data/orlando/simple

Other graphs that will be removed shouldn't affect the documentation

• [x] http://www.lincsproject.ca/cwrc/vocab
• [x] http://www.lincsproject.ca/occupations
• [x] http://sparql.cwrc.ca/ontology/cwrc

Need to update all queries to reflect changes from #543
