Form.delegateSubmit: invoke onSubmit() of nested Forms before onSubmit() of enclosing Form

[Florian Wunderlich]

It can be assumed that an enclosing Form in some way or another may 
depend on the state of an enclosed Form, but that an enclosed Form 
should never depend on the state of its enclosing Form.

Therefore, Form.delegateSubmit should invoke onSubmit() of the nested 
Forms (lines 1540-1553 in Form.java) before invoking onSubmit() of the 
enclosing Form (lines 1537-1538).

Is there any reason why this is the other way around at the moment?
