src/gcal-event-widget.c tooltip dates/times changed to a human-readable format;
The format was changed to be more human-readable as per request. Changes include include replacing month number with month name. The format strings are now also surrounded in _(), because of special formatting requirements of other languages. (e.g. czech dates: "22. ledna" require a "." after the day number.)
The currently used date/time format is not as readable.
