Deletion of unused libraries for old versions of Minecraft

Every version of Minecraft requires some libraries, often different version of same library.

With time, your .minecraft folder can use too much storage. You would have to delete "versions" and "libraries" folders, but it also deletes files needed for Minecraft version you actively playing.

This is bad, if you have bad internet connection.

I suggest adding a button that deletes all unused files such as <version>.jar in "versions" folder, or any library not used by any current profile.

This way, cleaning up your .minecraft folder and saving storage would be much easier and less painful (by less painful i mean you don't have to download again files you need, but deleted)
