Subject: [PATCH] This patch for the 7.0.2 JDBC interface addresses four issues
 I encountered while getting my reporting tool up and running with the driver.
 All changes are in the DatabaseMetaData class.

Problem: The getDatabaseProductVersion() method was returning "6.5.2"
Resolution: Changed it to return "7.0.2"

Problem: A call to getTables() with an unsupported table type (in the
String array) resulted in a malformed SQL statement and subsequent
parsing error
Resolution: Unsupported table types are now ignored without error

Problem: In a getTables() call, tables and views were both returned by
the "TABLE" table type, and the "VIEW" table type was unsupported
Resolution: Changed the "TABLE" type to return only physical tables and
added support for the "VIEW" table type (returning only views)

Problem: The getIdentifierQuoteString() method was returning null
Resolution: This method now returns a double-quote
