Allow free choice of "Start week on" day

[JohnVeness]

At the moment, there is a toggle for "Start week on Sunday", with the week starting on Monday if that isn't selected. But some cultures in different places around the world consider Saturday to be the first day of the week (see http://chartsbin.com/view/41671), and in general people may have their own preferences for this.

So, can you implement the user able to pick any day for the start day of the week?

I've just noticed that Simple Calendar has recently had this implemented (SimpleMobileTools/Simple-Calendar#2159) so yes, basically same as that but for Simple Clock! Thanks :)
