#555 Multiple child entry

[Birchy]

I don't remember if the java frontend (?GDBI) does
this, but I don't think it does.

Adding new info would be a lot less painful if a
special new form were developed to enter family info
en masse, especially multiple children. Marriage date
would be nice too. I realize that this would be some
complicated logic, as it involves adding and editing,
as well as multiple database records.
