/**
 * The generic "click" handler.  This function handles actions on any kind of
 * buttons that appear inside our calendar.  It determines the button type by
 * querying \em el.navtype.  The following types of objects are supported:
 *
 * - Date cells (navtype is undefined).  The function will select that date,
 *   add appropriate class names and remove them from the previously selected
 *   date.  If the date in the calendar \em has \em changed, it calls the
 *   calendar's onSelect handler (see the constructor).  If multiple dates is
 *   enabled, it will not unselect previously selected date but rather maintain
 *   an array of dates which will be avaliable to the onSelect or onClose
 *   handler.
 * - The Close button (navtype == 200).  If this is clicked, then the
 *   calendar's onClose handler is called immediately.
 * - The Today button (navtype == 0).  The calendar will jump to the "today"
 *   date and time, unless it's already there.
 * - The About button (navtype == 400).  It will display an alert with the
 *   "about message", as defined in the translation file.
 * - Previous year (navtype == -2)
 * - Previous month (navtype == -1)
 * - Next month (navtype == 1)
 * - Next year (navtype == 2)
 * - Day names (navtype == 100).  If any of them is clicked, the calendar will
 *   display that day as the first day of week.  It calls the "onFDOW" event
 *   handler if defined.
 * - Time parts (navtype == 50).  If any of them is clicked, this function will
 *   determine if it's a click or shift-click, and will take the appropriate
 *   action (simple click means add 1, shift-click means substract 1 from that
 *   time part).  Then it calls onUpdateTime() to refresh the display.
 * - Time scroll buttons (navtype == 201 or navtype == 202).  If such buttons
 *   are clicked, the time part involved is determined and it is incremented or
 *   decremented with the current step (default: 5).  201 is for "add", 202 for
 *   "substract".
 *
 * @param el [HTMLElement] the object being clicked on
