Converting old slugs?

Hey, the idea behind this plugin is to silently convert slugs when you create new posts, without loading your site with too much code. To add a menu page and the option to convert old slugs would add like a thousand lines of code, which would be needed just once per site. You can just re-save every post through the quick edit, or if you have a lot of posts – you can write your own function to do this, based on your specific needs.
