Special use cases of the IntegerEditor :

case 1
------

we have a required integer field without a default.

so the model will do set_value( None )

since this is a required field, the user should be able
to enter a value, 0 is a legitimate value.

when get_value is called, 0 should be returned if the
user has set the editor to 0, and None if the user didn't
touch the editor.

so the editor should make a visual difference between
None and 0, so the user can see he didn't enter something
yet

case 2
------

we have a non required integer field without a default

the model will do set_value( None )

the get_value() should return None and not 0.  because
in case it returns 0, 0 will be written to the db, causing
an unneeded update of the db.
