Added a method that exposes DataGrid's ScrollPanel, to allow some customization by subclasses.

Added a way to put a widget inside of the scrollable area of datagrid to allow
placing pagers, etc.

Context: the goal is to put a footer in the middle section so it will scroll
into view below all the data rows.

File user/src/com/google/gwt/user/cellview/client/DataGrid.java (right):

http://gwt-code-reviews.appspot.com/1864803/diff/1/user/src/com/google/gwt/us...
user/src/com/google/gwt/user/cellview/client/DataGrid.java:846:
tableDataScroller.setWidget(message);
It seems like this is going to replace whatever changes you make to
tableScrollPanel. Do you want explicit support for putting a footer on tableData
instead?

FYI, there's an issue for that:

(understand: whose status should be updated)

Thanks, that's exactly this issue. I have a UI problem though - I do not see how
to link this change with the bug.

FYI, there's another issue which is somewhat related:
http://code.google.com/p/google-web-toolkit/issues/detail?id=7589

(and I've updated the issue status)

Please let me know if you would prefer IsWidget, or UiObject there.
