#1 Field Type Conversion needed

[Guido Beutler]

rdbs2j can not deal with int and Interger types at the
persistence viel layer at the same time. For dealing
with foreign keys which are nullable it is required
that the fields get the type Interger because int can
not represent a null value. Currently all sql int (and
short etc.) are mapped to the java type int. This
mapping can not be changed by the gui of rdbs2j althogh
the objectmodel could manage it.
