blackbox: properly replace ui class
Without this, anyone creating a ui object using: uimod.ui()
skips the blackbox.
Also, anyone doing ui.copy() skipped the blackbox.
Unfortunately, the ui object lifestyle is a bit messy,
the first one that's created is never actually initialized
with subclasses, instead pieces of the subclass are adopted
into the primal ui object. In order to handle this, a
_partialinit method will be called to ensure that the
blackboxui is properly initialized.
