Introduced renderer that exteds h:form renderer to render the hidden input fields required by some ice:* components. Introduced also system event listener that changes the h:form renderer to the overriding render.

Introduce FormEndRendering utility to allow rendering of markup right before 'form' end tag is rendered. Use utility to render the hidden input fields required by some ice:* components.

Modified DOMRenderKit so that FormBoost is applied to all requests for a Form Renderer.

It may be necessary to add an ICEfaces View check around deltaSubmit rendering code.

Turn on deltaSumit functionality in the client only when the view is ICEfaces enabled.

Icefaces2 revision# 22161
Server: Tomcat6
Browser:FF3.6, IE8 & Opera10.60

Problems common on all browser:
1)Drag & Drop not working
2)Popup Panel: Draggable popup can be dragged only once
AutoCenter is not working

Problem on FF3.6 only:
1)RichText: application tries to reload the page when user tries to save text in RichText.

Problem on IE8 only:
1)''Server Internal Error' is seen when trying to use Buttons and Links
Also following is displayed on the webpage:
viewId:/showcase.jsf - View /showcase.jsf could not be restored.
class javax.faces.application.ViewExpiredException

Render icefacesCssUpdates input hidden field using a FormEndRenderer since DnD and popup panel rely on it.

Check for the existence of Ice.FCKEditorUtility variable in the evaluated sent by InputRichText renderer. When InputRichText is used for the first time Ice.FCKEditorUtility is not yet loaded causing a JS error that stops onAfterUpdate listeners from being invoked. In turn ViewState hidden field is not written thus the following submit will trigger a full page update/reload.

The IE8 issue can be replicated only when using the 'Reset' button in 'Button and Links' panel. The cause of the exception on the server seems to be the missing value of 'javax.faces.ViewState' parameter. The 'javax.faces.ViewState' field is added dynamically to the updated form without defining a defaultValue attribute for it. When the form is reset the value of 'javax.faces.ViewState' input element is set to its default value, the empty string, which will trigger the exception when the form is eventually submitted.

The applied fix sets also a 'defaultValue' for the 'javax.faces.ViewState' input element so that a form reset will reassign the same value (the view state key) to the input element.
