multi: Add comment versioning

[lukebp]

It has become apparent that adding comment versioning would be a useful feature. There are multiple instances on pi of comments that were made erroneously or comments that have mistakes/typos in them. It would improve overall UX if a user is allowed to edit their comments.

This feature would be similar to how github comments work. A user would be allowed to edit their comment, but all prior versions of the comment would still be publicly viewable.

This will require changes to politeiad, politeiawww, and the cache. A rough outline of the work that would need to be done:

• Add an edit action to the comment journals
• Update the cache to store all versions of the comment
• Add politeiawww routes for editing a comment and for fetching previous versions of a comment

I'd be interested in tackling this if it's still open.

This issue is still open, buts a pretty big one. It will require significant changes to politeiawww, politeiad, and the cache. As a newcomer to the project, I'd prefer if you worked on some smaller issues first before tackling something like this.

@al-maisan are you on the decred matrix server?

[martonp]

@al-maisan are you working on this?

[al-maisan]

Nope. See @lukebp 's comment above.

[martonp]

Ok I'll work on this one

[lukebp]

@martonp this is a large issue. If you're going to tackle it you need to first post here how exactly you're going to do it and then break it up into smaller PRs that can be delivered individually.

[martonp]

@lukebp Sounds good, I'll do that.
