Move XML class to internal PIM

Add namespaces!!!

Opie::Core and Opie::Core::Private
Opie::Net  and Opie::Net::Private
Opie::Ui   and Opie::Ui::Private
Opie::MM   and Opie::MM::Private
Opie::DB   and Opie::DB::Private

PIM classes are not yet converted because we will do other work
on it as well

 //   Yes, I could have merged them, but then the excellent performance of
