#1 Enable queries to be linked together

[Peter Ansell]

* Handle linked query types, with a single master URI triggering a serial set of query types to be utilised with the results chained between them according to SPARQL templates
** Add the type of the query template to the query type definition, ie, ASK, CONSTRUCT/DESCRIBE, and SELECT
** Utilise the results of the query, ${queryResult_VARIABLE} to determine using some internal method whether subqueries should be run, and run them by instantiating the atlas2rdf.jsp using a URI, and simply use the final results of that as the join for the main query which is calling sub queries
