We need to extract the essential interface between the front-end and back-end of webdatabase objects in order to implement proxy objects that will handle the IPC between the 2 ends. This patch introduces the AbstractSQLStatement and AbstractSQLStatementBackend which defines that essential interface for the SQLStatement and its backend.
