Automatic Post Slugs for Forum Posts

[WisTex]

While the item and display views use long post ids in their URL, the forum post view page should use post slugs instead.

1. The post slugs should be automatically generated based on the title of the post.
2. Each post slug should be unique, appending a number after duplicate titles, if necessary.
3. Both the forum topics page and the forum post page should use slugs instead of the post id.
4. The post id should still work if there is no slug, for some reason (like it has not been created yet).
5. If the post does not have a title, provide an alternative means of creating a unique slug.

Note:

The slug is only meant for viewing the post on the original forum and is only used for linking back to the original post on the original forum. It is not intended to replace the unique post ID used for federation.

The purpose of the slug is for SEO purposes, and to make the URL look more friendly, and possibly shorter.
