[Twisted-Python] woven-bug: multiple nodes using the same model

[Paul Boehm]

ok,

this fixes at least the problem with List repeating the same
element all over (instead of listing all elements).
(patch made against my local tree, also contains added CheckBox
functionality).

i'm still working on the problem that the view lags behind the model.
