Renaming Subject

### Problem

### Many subject have multiple different duplicate, e.g. _Ernest Rutherford (1871-1937)_, _Rutherford, ernest, 1871-1937_

### Subject page has an edit button that could be facilitated to rename that subject in any edition


Example:

Go to subject page _Rutherford, ernest, 1871-1937_, Edit-Button, change title from _Rutherford, ernest, 1871-1937_ to _person:Ernest Rutherford (1871-1937)_, save button.

After saving, the subject should be changed in all edition with the former subject.
