/*
    The default style of these tabs is that of an NSTabView with tabs at
    the top in the "regular" size. These tabs can be used with or without
    a tabbox element.
    For bottom tabs you should use the "tabs-bottom" class on the tabbox
    or the tabs element. Bottom tabs use a style that's similar to the
    one used in Adium.
