[Seaside] Porting

[Lukas Renggli]

Not much, you just use CPS (continuation passing style) to define flow.

So instead of

  result := self call: aComponent.
  result doSomethingWithIt.

you write

  self show: aComponent onAnswer: [ :result |
    result doSomethingWithIt ]

CPS gets nasty with complicated flows (loops) and when other (library,
model) code is involved, but a transformation is always possible. So
it is strictly equivalent.
