More work on the report widget

• Connected the tree navigator to the report, so clicking an item in the tree now expands the appropriate node in the report
• Created a SelfLabelingTextInput which when it is empty and not focused, it displays a label in itself such as ‘Search’.  I had to remember how to create and set custom styles in flex components.  Checked to make sure it is still the same method in Flex 4 as it was in Flex 3.  There’s decent sample code of how to do it in SelfLabelingTextInput.
• Created a skin to the text input which has a space for an icon, added a standard magnifying glass icon, and called it SearchTextInputSkin, both the skin and the component are now in FGMUtils.
• Added the ability to disable the transition animations in rollupcontaienrs so I can correctly calculate the verticalScrollPosition after expanding nodes
