Build 2305 is available

The highlights of this new release include:

* Support for importing/exporting R2RML mappings
* Support for automated mapping generation as defined by the "Direct Mapping" W3C specification
* Various options for data materialization (similar to dump-rdf in D2RQ)
* Support for concurrent queries in the SPARQL endpoint through connection pooling
* Better support for Oracle, Postgres, SQL Server and DB2
* Improved the SQL queries generated by Quest by avoiding some operations when unnecessary (e.g., casting), and placing optimally the JOIN conditions in the SQL query.
