KeyHandlers for ScrollTable

Description:
Implement KeyHandlers (other event handlers) for ScrollTable or for the 
datatable (FixedWidthGrid) of the ScrollTable.

Detailed description (please be as specific as possible):
Bring the new event architecture to the ScrollTable/PagingScrollTable by 
having them implement some logical event handlers (e.g. key handlers). Use 
case: using the arrow keys to navigate the "selected" row or cell of the 
table or pressing enter to edit the cell using the CellEditor.

Currently using:
GWT Incubator drop for GWT 1.6

Example code snippet:
dataTable.addKeyDownHandler(new KeyDownHandler() {
    public void onKeyDown(KeyDownEvent event) {
       // maybe include some information about the previous and new
       // selected cell and row(s) in the key down event
    }
});

Current workaround:
Put the entire ScrollTable in a FocusPanel and add a KeyDownHandler to the 
FocusPanel to listen for key events for the table. However, then, we must 
explicitly set the focus back on the focus panel after certain events (e.g. 
closing a dialog or popup box) in order to begin handling the key events 
again.
