Make all AccountsMenu items BitmapMenuItems

Now all account menus will have the pretty protocol icons to go with
them. :)

The icons are scaled to text-size so that they might be displayed in a
corresponding MenuButton, or maybe BMenuField at some point, and put
into the ImageCache.

The menu items do not have ownership of the bitmaps.
