Ok, attached something that makes the above work. Note, the patch is far
from finished, just enough for this example.
This idea is to store a KParts::ReadOnlyPart pointer and a DOM::Node of
the frame in its parent document in KJS::Window instead of only the
KHTMLPart pointer of the frame's document.
If the frame's part is destroyed and DOM::Node handle is not zero (I'm
not quite sure that if node is detached, this handle becomes zero *), a
possible new KPart is search in this handle's document. If one
is found and it's not a KHTMLPart, still some functionality can be uses.
Such as changing the url (emit openURLRequest on its browser extension)

What needs to be done is make sure that *) is correct assumption (and do
I need getDomNode()?) and also allow document.frames[0] to work for frames
that are transformed to other KParts (in the above case it works because
of the 'frame' variable). Also some other properties, like frame dimension,
could work for other KParts.
