Show corresponding modlog entry when viewing deleted posts/comments

[codenyte]

Requirements

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

Describe the feature you'd like

Show corresponding modlog entry when viewing deleted posts/comments, instead of just displaying an error message. Or at least show some indication that the post was actually removed, not just that it can't be found. The API does the same, so I think the official UI should also do this.
