Java Application Framework For All Source

Made the following changes:
a- Used pageContext.REQUEST_SCOPE when invoking pageContext.setAttribute()
b- Replaced 'pageContext.getAttribute()' invocations with 'pageContext.findAttribute()'
This was done to allow Jaffa widgets to be spread across multiple JSPs in template environmnents like the TILES framework. This would allow us to paint the FormTag in a Layout JSP and the widgets in the inner Tile JSP.

Added a bug-fix on behalf of JonnyR

Fixed to stop javascript errors on mouseOver events for the tooltip when page hasn't finished loading

Documents the differences between Struts and Jaffa

This file will be a running log of all the changes being made to JAFFA since version 1.2

Added error message for ComponentExpiredException

This exception is thrown by the PortletFilter, when an invalid componentId is passed in the request stream

A ServletException will now be thrown instead of forwarding to a hard-coded error JSP

Added sample upload and thumbnail code
Added domain object patterns and generated code
Refactored build scripts
