Create a "blank" activity

The "blank" activity is needed in the adaptative mode, to display white space between scheduled activities.

It is very simple, you just have to create an activity with the name "blank" (without quotes!) and define a default duration you'll be able to override in the timetable.

1. Create the activity
2. Insert it in the schedule like any other activity (change the duration if needed)
3. See the result
