commit 2423b30ee46c12f92051c4f2a096532e55752c46

    Implement API Level styles.
    This changes the way we show the API Level for a given package/class/member.
    It also provides hooks in the document to allow us to restyle items
    based on a user-selected API Level (show/hide available items).
    More changes to provide the toggling feature will come soon.
