Schedule

Allow to have different versions of the schedule.

Add an extra level to show how tasks are split among artists.

Current implementation allows to drag tasks per each artist in gantt grid which is great (task dates updates accodingly). But it lacks ability to change dates individually by stretching/shrinking the selected bar which eliminates half of potential usefulness.

As title says it would be very convenient for Artists to know their plan for tasks they are assigned to in a form of Gantt chart like it's presented in Main Schedule.

Add more bird view zoom level for long productions
