Make possible task span several hours

[Hopsakee]

For planning a day, it would be neat if a task taking two hours also spans 2 hours on the calendar. That way I can easily see if the tasks I planned for that day will fit in the day.

Ik would even better if the length of the task would be automatically determined based on the ([time estimate]) notation in Trello. e.g.
Task title: Do the dishes (3)

Sorry, this would break the current way the day view is handled
