Add option to starr a post in list of posts

[pitscher]

Hey, I just started to use this theme and I really like it.

I would like to have the option to starr (hope this is the correct word to depict this 😄 ) single posts to attract a visitors attention.
The author can starr a post by setting the value of a new variable isStarred of a posts front matter to true.
This will cause a little star to appear right next to the title of a starred post in the list of posts.

By the way: I already implemented this for my blog.
Checkout the attached picture.

Having an option to starr a post is a great idea. Please create a PR for this.

Here you go: #223
I also made sure the star is actually centered - missed to do this for my implementation. (You might see it if you take a close look at the picture I shared 😅).
