/**
 * A custom adapter designed to fetch bookmarks from a cursor. Before Honeycomb we used SimpleCursorAdapter, but it assumes the existence of an _id
 * column, and the bookmark schema was rewritten for HC without one. This caused the app to crash, hence this new class, which is forwards and
 * backwards compatible.
