[Seaside] Seaside updater

[Gerhard Obermann]

Now simplified with updater only!

 | formId |
 formId := html nextId.
 html form id: formId;
  with: [html checkbox value: false; callback: [:v | set := v];
    onClick: (html updater id: 'text'; triggerForm: formId;
       callback: [:r | set ifTrue: [r text: 'My address'] ifFalse: [r text:
'']]).
     html textArea id: 'text'; with: [html text: 'Empty']].
