Extend hasGeometry to allow for GeometryCollections

[nicholascar]

This change is requested to allow for more sophisticated representations of the spatiality ofFeatures. Ultimately, this change will allow for a form of fuzzy (uncertain) spatiality by usingGeometry Collectionsof relatedGeometry` objects.

This PR also:

• updates the version numbers of GeoSPARQL in this branch from 1.1 to 1.3
• fixes some small ASCIIDOC formatting and referencing issues
