Make post URLs more meaningful

[kevinhikaruevans]

Requirements

• [X] This is a feature request and not a bug report. Otherwise, please create a new bug report instead.
• [X] Please check to see if this request (or a similar one) already exists.
• [X] It's a single feature. Please don't request multiple features in one issue.

Describe the feature you'd like

It would be nice to have post URLs that:

• have the community in the URL
• have a URL slug generated using the post's title

Whenever someone links a Lemmy post, I have no idea what the content will be from the URL. It would be nice if the URL gave clues to what to expect in the post.

Instead of having https://lemmy.example/post/1234, I would like to see https://lemmy.example/c/some-community/post/1234/this-is-some-thread (or something similar).

Yep, this would be a huge improvement. It would be a usability improvement and it would be an SEO improvement too.

somewhat related, dealing with changing the post URL format

it would probably be best to do these changes at the same time

I believe this is a backend issue and a duplicate of Community name in post URL

[kevinhikaruevans]

It's a duplicate but it's both a frontend and backend issue.

The route is defined here: https://github.com/LemmyNet/lemmy-ui/blob/c49ca9e1958622600f615c276d599d70aa6ccda5/src/shared/routes.ts#L69-L73

Then the Post and HttpService will need to be updated.
