    Expose tablet pad modes as properties
    
    There is not good wire protocol for pad modes so instead we just export the
    information via properties. One property to tell us how many groups and how
    many modes each group has. One property for the current mode of each group.
    And three properties to tell us which group each button, ring and strip is in.
