Use trait collection to decide which form of weekday symbols should be used

[xhacker]

Currently RSDayFlow uses isPhone and isPortraitInterfaceOrientation to decide the form of weekday symbols. It mostly fine, but has problems when the view is in split view.

The best way is to use trait collection. However it requires iOS 8. Another workaround is to use the width of the view. Thoughts?

We can try to have another look at this PR or add support for trait collection on devices with iOS 8+.

Hi @xhacker,
Are you planning to make any PR for this?

[xhacker]

Is it acceptable to support only iOS 8+?

I just looked at this PR and realized it's very flexible. I could make a PR based on that without using trait collection. But I don't have time until this weekend.

Okay, I'll do it myself.

[xhacker]

Okay, thanks!

[ruslanskorb]

No probs!

Awesome, thanks! 👍
