Does the Skin work if you comment out this metal:block?

Yes, this could be a bug from me. It could be that this is a mistake
in the pagelet. Perhaps the "commontask" pagelet calls the Adding items
and this will run into a error. I don't remember exactly but the
macroname == 'view' is something I have on my todo list for refactoring.
This was just a quick solution but it needs some better check for display
the IContextMenu pagelets. This will be the next step to implement.
(nested context menus)

The Boston skin is in a real experimental state right now.
I think I can work on it at the end of this month and finishing
the menu part and implement preferences.
