Bug 19263: Rancor - 001 widget - db update

    In advanced editor mode for cataloging, the 001 widget will
    automatically assign the next control number if a format is defined
    in  authorised_values table.

    To test you need access to the database.
    1) Verify that a new entry for CONTROL_NUM_SEQUENCE is added to
    table  authorised_value_categories
    2) Enter a new value for authorised_values with the authorised_value
    column ending in a number
    3) Edit a record using the advanced editor, specifically the 001
    field
    4) Note the new widget and option to increment or assign manually.

    The buttons fit within the widget now, and there's a database update
    to create the CONTROL_NUM_SEQUENCE.
