[Seaside] Using Dynamic Bindings in Seaside rendering

[Derek Brans]

Ooops, the point of clamping is to isolate a binding to the execution of a
block.

This should be
renderContentsOn:
     html form: [
                  Bindings clamp: [
                        #myAttributeForm binding: self.
                        self renderFormContentOn: html].
     html submitButtonWithAction: [self submit] text: self submitButtonText]

The binding remains in scope for the duration of rendering, but is not
present in a callback block (unless the home context of the block is in a
rendering method, I suppose).
