Ensure weekday labels respect the locale’s firstDayOfWeek

[makenosound]

I noticed today that the firstDayOfWeek locale setting isn’t respected by the weekday headings.

This change passes through that prop to the <Weekdays> component and then appropriately normalises it to a 0-6 integer using the modulo operator so that they do match up to the dates below.

Thanks! Is it possible for you to add a test to reproduce this? I believe it is a fix for #207 – I need to investigate this bug better, but it looks it is a potentially breaking change.

@gpbl Yep, will add a test when I get a chance!

I don't think it should be a breaking change though, since it's just passing through some additional data.

@gpbl I’ve added a test for that now, and yep, it should fix up #207.
