as a scrummaster,
i want to optionally specify the end date of the sprint
so that the graph gives me a more accurate overview of the sprint

### done if
* i can specify a start and end date for the sprint (start, default = today)
* a day is created for each date
* a day is allowed to have no values (MD/SP/BV)
* the sprint velocity doesn't take blank days into account
