Implement scrolling in the appointments panel

Browse Source 
With multiple days in the APP panel, up/down movements should change
behaviour at the top and bottom of the list displayed, and load the
previous/next lot of days.

This requires that the move function returns the result of the
operation.  Furthermore, the ability to move the selection to the
beginning of a day is needed when moving down (in order to move from the
first day to the last day).  For this reason a DAY_SEPARATOR has been
inserted also after the last day of a lot.

Appointments have a listbox height of three to separate them clearly
when there is more than one in a day.  This leaves a spurious empty line
at the end of a day with appointments.  The DAY_SEPARATOR height is
reduced from two to one, and a new EMPTY_SEPARATOR of height one is
inserted in any day with only events.

When scrolling up the DAY_HEADING becomes visible when the selection
reaches the first item of the day.

The length of the separator (between events and appointments) is
adjusted to leave a space to the window border at both ends, thereby
making it a part of the day, not a separation between days.

The dummy event must also be recognisable when not the selected item and
is only inserted in interactive mode.

The test for a saved selection must also recognise caption items which
have item pointer NULL.

The function day_get_nb() has been renamed day_get_days().
