Make parse_date accept several short forms.
Short forms are only accepted in interactive mode (e.g. when using the "Go to" function, editing a recurrent item's end date, and so on). Samples: "1/1/30" for "01/01/2030", "26" for the 26th of the currently selected month/year or "3/1" for Mar 01 (or Jan 03, depending on the date format) of the currently selected year.
