Use xsd:anyUri not ""@ for URI literals

[nicholascar]

In GSO Elements, each element class declared has a property gsel:chebiid indicating the CHEBI URI for the same element, e.g.:

gsel:nobelium
  ...
  gsel:chebiid "http://purl.obolibrary.org/obo/CHEBI_33396"@en  ;
  ...
.

The URI is absolutely not an English string!

Better would be:

gsel:nobelium
  ...
  gsel:chebiid "http://purl.obolibrary.org/obo/CHEBI_33396"^^xsd:anyURI  ;
  ...
.
