Log Message: 
-----------
Add down state to IGridItemRenderer. Added down state support in GridColumnHeaderGroup for UI feedback. Also, fixed various bugs relating to the header renderers.

IGridItemRenderer.as, GridItemRenderer.as, TextFieldGridItemRendererInclude.as
-Add down property

DefaultGridColumnHeaderRenderer.mxml (Both spark and wireframe)
-Add back missing showTruncationTip property.
-Modified the states to be GridItemRenderer states. This gives us the UI feedback like a Button
-Only include the sort indicator in the layout when its visible so that the sort indicator doesn’t overlap the header text. 

GridColumnHeaderGroup.as
-Added downColumnIndex, hoverColumnIndex to support the header renderer states. I modified the mouse handlers to handle these cases.

GridColumnHeaderGroupLayout.as
-Added initalizeItemRenderer to set the properties on the header renderers using the down/hoverColumnIndex from GCHG.
-Fixed a bug in getHeaderIndex() so that we return the correct header if the x is past the end of the grid but still over the vertical scroll bar.
