Several Bugfixes

This release makes several bugfixes and clarifications to the autocatcher's setup guide.
The following are the most notable examples of things that were fixed:

• The replit branch now actually works with replit, and a repl.it example has been made (feel free to fork it): https://replit.com/@devraza/catchtwo
• Extra/missing files have been removed
• The release .zip files now only contain what you need
• The spammer sends a string of characters properly

Clarifications made:

• Removed unneeded information
• The replit version's README.md now has instructions that detail installing the autocatcher in repl.it

Features added (it's not much):

• The autocatcher sends a more complicated, random string of characters
• The repl.it version now has secrets, allowing you to run the bot without worrying about people looking at your id. The instructions to set up secrets are in the README.md in the replit branch.
