Hiding global blocks on different devices

We added an option to hide global blocks on different versions of a website, which will allow you to create separate versions of headers and footers for desktop, mobile, and tablet versions of sites. 

It means that you can create several global blocks with varying content and hide each one of them on the required versions. Moreover, you can hide blocks on several versions at the same time, which will allow you to adapt the website more conveniently.
