[VIVO-1312] Implement Linked Data Fragment Server (#53)
* [VIVO-1312] Linked Data Fragments initial implementation * [VIVO-1312] Use known ontologies in the prefixes config * [VIVO-1312] Simplify SPARQL as when restricted to specific values, they don’t need ordering * [VIVO-1312] Freemarker fixes * [VIVO-1312] Remove blank nodes * [VIVO-1312] Add access control header and standard prefixes for TPF * [VIVO-1312] Render literals in form so that they will work on resubmit * [VIVO-1312] Minor template update * [VIVO-1312] Minor template update
