Implement scrolling in the appointments panel
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().
