Reverts development branch to last successfull build

RestyGWT looks ok as a general purpose json serialization
library, but I think we'll be better of writing a bit
of hand-rolled serialization code until we know better
what the whole finished data model will look like, and
then we can look again at code generation.

I think one lesson I've taken for the exercise is that
simple overlays over the data won't be sufficient for many
of our model classes like FormClasses, or FormTrees etc.

For these cases, there is a distinct process of going from
the pure, flat data to richer data structures that are
coupled with behavior. If we restrict the "models" to flat
json-like structures, we'll probably end up creating parallel
richer data structures for solving problems.
