Refresh styling of ToDos when Orage is toggled on.

ToDos have different stylings in the list under the calendar in Orage's window (ongoing ToDos are blue, completed ones are red and normal ones are black). However, if the status of a ToDo changes (ie: the due hour passes), its styling is not refreshed accordingly unless either Orage is closed and relaunched or the entire list is refreshed by adding, removing or editing a ToDo item.

Using Orage as intended (with the clock panel plugin firing the "orage -t" command), this means Orage never updates once it's launched at startup, unless it's done manually. Is it possible to have it refresh when Orage is toggled on (checking if start and end date-hours have passed and restyling accordingly)? I think this is the last thing that bothers me with Orage. Great work otherwise!
