Disabling "Sunday" when firstDayOfWeek is Monday

[alexbusuioc]

This is very simple to reproduce. Just set the DayPicker to start with Monday as firstDayOfWeek,
and try disabling "Sunday" (index 7)

<DayPicker
firstDayOfWeek={1}
disabledDays={[ { before: new Date()} , { daysOfWeek: [6,7]} ]}
/>

In the example above, only "Saturday" will be disabled

oh, silly me. Sunday has the index "0", not "7"

It can happen to anyone from EU working with US code ^_^
