Feature summary (what you would like to be able to do and where):
I would like to be able to sort the references by name in the main list of references, instead of just by order in which they appear in the article.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):

When I translate articles from enwiki sometimes some of the references are duplicated, so, instead of being <ref name=":1"/> let's say, they become a copy of the <ref name=":1"> with all the parameters. It would be great to be able to see if there's more than one reference with the same name, so we can check if they're exactly the same and in that case, solve it ourselves. However, especially in articles with a lot of references, it's difficult to do that. Also sometimes, when people create their own articles, or someone edits another article, they might add the same reference as well without realizing, and this feature would help people in realizing this.

Of course, another opcion would be solving this via the normalizing article feature in ProveIt. It would be great to be able to have it notice if there's two references that are exactly the same, name and everything, and fuse them somehow.

Benefits (why should this be implemented?):
It would allow to unite references that are the same, so the list of references reflects correctly the different urls used in the articles.
