    Configurable cell_class in DataTable

    There are two changes in this proposal. One is to move the logic
    for extracting cell data from the row datum (and handling auto columns)
    to the Cell class, into a separate method for easy extending. The
    second is to make that extending possible by making the cell class
    configurable in the DataTable's meta.

    Those changes are supposed to make it easier to extend the DataTable
    with new kinds of cells -- for example, cells that contain an editable
    widget, a progress bar, an icon, etc. as well as make it easier to
    modify the behavior of the auto columns -- for example, by making it
    possible to have some of the multi_select checkboxes preselected. Those
    changes would also make it easier to integrate DataTable with a Django
    FormSet.

    Right now, in order to modify any of the proposed Cell.get_data
    behavior, one has to make their own Row class and practically copy-paste
    the whole Row.load_cells method, as there is no easy way to extend it.
