Style: Default Theme: Should Support Dropup Menus

[Diana Whitten]

Bootstrap supports dropup menus in addition to dropdown menus, seen here: http://getbootstrap.com/components/#dropdowns

Right now, our little dropdown arrow only works for drop'down' menus.

    Default theme lacks support for dropup menus

    The default theme assumes ALL dropdowns are drop'down' menus, however
    Bootstrap supports dropup menus as well. This simplies the logic in
    the theme's dropdown.scss file in order to support all Bootstrap
    types.

    Also, added the dropup to the theme preview page for ease of testing.
