New setting: hide sidebar for article

[LennyObez]

Hey there,

In "Material for Coders" theme, we can show or hide sidebar but that's all, you can't define a paramater like: "hide for article, show for whatever else".

I would like to make my article without disturbance. So I would like to hide sidebar when the page is an article.

In other way, the "menu-2" which is under the blog name disappear on article, I would like it to stays.
