Dynamic handler can now use preparedStatement to define the SQL request (not only a string)

### Context
Dynamic handlers (SQLHandler with a query built from a factory) can only use a string to define the SQL request but all queries are not compliant with Sybase, Oracle and MySQL (date format, convert functions...).

### Description
SqlHandler generated can now define a factory that implement the StatementBuilder interface (from codjo-mad).

``  
<query factory="net.codjo.workflow.SelectAllWorkflowLogStatementFactory" statement="true"/
