Handful of changes to NativeControl, TreeView and TableView I'm going

to need for the bookmark manager. Specifically:

. NativeController now delegates OnContextMenu to the
  ContextMenuController.
. TableView allows a NULL model.
. TableView::SetColumns was buggy.
. Added a method that TableView invokes after painting.
. Added methods to TreeView for getting various state information.

BUG=674
TEST=make sure the various places in the UI we uses trees and table
  work fine: cookies table, passwords table, task manager, bookmark
  editor, search engines.
