Some of the code which implements the To-Do list gadget

Several different functions are defined for this gadget; one such function — loadToDos110 — will be called on load; this function also gets user preference values as discussed. Another of the functions — addToDos110 — will be called on submission of a related form. Other functions still are only invoked internally (e.g., getPriorityText110, sortByPriority110, ...), i.e., by other functions defined within this same script.
