Permalink Trailing Slash Fixer

When your permalink structure does not end by a trailing slash (/), all your links look like http://example.com/2009/05. Permalink Trailing Slash Fixer add the missing trailing slash.

Example

If you have a site with the following permalink structure /%category%/%postname%.html and your permalinks
look like these:

1. Single Post: http://example.com/my-category/sample-post.html.
2. Category: http://example.com/my-category.
3. Archive: http://example.com/2009/05.
4. Page: http://example.com/about.

After activation of the plugin:

1. Single Post: not modified.
2. Category: http://example.com/my-category/.
3. Archive: http://example.com/2009/05/.
4. Page: http://example.com/about/.
