- timerlist: don't discard unsaved user-changes at timers silently

- some more small changes/fixes:
  * don't allow reminder-timer with standard message text ("---")
  * fix display of changed recording directory
  * use addIntroItems() function in menus
  * fix dependency of menuitems in apids-menu
  * use pulldown-mode to choose timer-type
