[BOT] Automatic blacklist

[derekantrican]

When someone fills out the Google form requesting to be blacklisted, this should be done automatically. Something like this:

1. User fills out form
2. Google Apps Script behind the form responses spreadsheet triggers on the new response and sends the request to my server
3. My server [stabilization needed first] handles the request and updates the BlacklistedUsers.txt file for the bot
4. The server? (maybe keep it in the bot code?) will then send a message to the user letting them know that they have been blacklisted (with different messages for each level of blacklist)
