f388f27b - Abstract virtualBuffer table navigation support so it can be available in all browse mode documents.

Abstract virtualBuffer table navigation support so it can be available in all browse mode documents. If an API has the ability to look up a cell by row and column (and correctly handles row/col spans) then only BrowseModeDocumentTreeInterceptor._getTableCellAt needs to be overridden. For more complex cases, BrowseModeDocumentTreeInterceptor._getnearestTableCell may have to be overridden.
