Editing content should be consistent throughout the site

[rylandg]

Is your feature request related to a problem? Please describe.
Both posts and comments on posts are editable, but direct messages between users are not. Regardless of preference (twitter style of no editing or slack of edit everything), the UX should be consistent throughout the site.

Describe the solution you'd like
Make direct messages editable (keep history if worried about abuse).

Describe alternatives you've considered
Technically you could make comments uneditable because it would be consistent. Please don't do that though.

Thanks for the issue @rylandg. We'll discuss this as a team and come back to this.

@Zhao-Andy Of course, thanks for taking the time to think it over!

Thanks for the feature request. It looks like DMs are editable now.

Since we are working on cleaning up stale issues and I think this one is actually fixed I am going to go a head and close this.
