//   -Create and fill the applet struct.
//   -Set the config pointer, and maybe some actions.
//   -Register (dock to) applet events (See cdtype.Events for the full list).
//   -Declare and load permanent items required during all the applet lifetime.
//    (those who do not require a config setting, unless it's in a callback).
