[DbUtils] ListHandler

[Mikhail Krivoshein]

There is one problem with my idea.
If we have say ScalarHandler and my ListHandler when question arise: who 
is responsible for scrolling ResultSet rows?
I guess ScalarHandler does and ListHandler need to assume that 
ScalarHandler will scroll by one row.

So fixed ListHandler code will be:
=====================
   public Object handle(ResultSet rs) throws SQLException {
       List result = new ArrayList();
       while(!rs.isAfterLast()) {
           Object o = rowHandler.handle(rs);
           result.add(o);
       }
       return result;
   }
=====================
But here there is another problem. As I know not all drivers supports 
isAfterLast() method.

I appreciate any comments about ListHandler idea and solutions for my 
problem (reuse as much code as possible when
generating custom lists).

Best regards,
Mikhail Krivoshein
