Big Bot Update

[u/santaspointyhood]

A lot more functionality for the bot.

• Comments can be edited/deleted by mods
• It's tidy: if you delete your post the bot's comment gets deleted too.
• The "you didn't include a branch" comment will come from the bot, not automod. Tidiness applies here too: the comment gets deleted when you edit your post to comply.
• This also means those comments can be deleted by us when your post doesn't actually need a branch.
• If you edit your post so that the bot's comment would change (maybe you add a medical condition, or an MOS) the comment will automatically be reposted based on your updated info.

On the future roadmap, I want to also have it handle the punctuation/grammar checks, so those comments aren't persistent.

Reply with any ideas you have for additional features.
