jdbc driver: Support for 'BOOL'

Problem:   If try to use field of type "java.sql.Types.BIT" obtains error "Unknown
Types Value"

Resolution:
   Add this:
   PreparedStatement.java   460,461d459   <                       case Types.BIT:   <
set(parameterIndex,
((Boolean)x).booleanValue() ? "true" : "false");
