[Seaside] some trouble getting started

[Tassilo Philipp]

Ok, I figured it out - the registerAsApplication message has to be sent to the class and not the class' instance, of course, and about the halos: in the seaside version I'm using it seems to be a decoration and not a toolconfig... however, the halos seem to be partly broken on GST :(
