  Notes:
  - You can turn off arrows.
  - You can pop the pane right,left,up,or down.
  - For each of the above, you can align the pane four ways; for
    the case of popping it down:

    MENUBUTTON_ATTACH_LEFT:     MENUBUTTON_ATTACH_RIGHT:

     +------+                        +------+
     |Button|                        |Button|
     +------+---+                +---+------+
     |   Pane   |                |   Pane   |
     +----------+                +----------+


     MENUBUTTON_ATTACH_CENTER:  MENUBUTTON_ATTACH_BOTH:

       +------+                  +----------+
       |Button|                  |  Button  |
     +-+------+-+                +----------+
     |   Pane   |                |   Pane   |
     +----------+                +----------+

  - The width (height) of the pane is taken into account by getDefaultWidth()
    (getDefaultHeight()), so that the button will stretch to fit the pane.
  - You can specify horizontal or vertical offset to position the pane away
    from the button a bit.
  - Should it grab first before doing the POST?
  - GUI update disabled while menu is popped up.
