[Request] Snap rotational alignment mode

[Teu3hgb]

When you rotate an object, it's pretty difficult to get perfectly aligned with other objects.

I suggest adding a "snap" rotation mode, that snaps to the nearest 45th degree cardinal direction, similar to what you would find on PhotoShop or Paint.NET when holding the shift key and rotating.

Similar to those programs, I recommend the mode be active when you hold the shift key.

Thanks for the suggestion, I will look into it.
