    [AppIcon] redo constructor to take a params object, add "size" param
    
    Add a "size" parameter to allow changing the AppIcon size, and then
    simplify the constructor by taking an object with parameters like
    gobject-introspection constructors do, rather than taking a large
    number of miscellaneous arguments.
