Handle commands from Admin

[Katreque]

Create a command handler to the bot.

• Check the bot prefix in the .env.
• Detect the bot commands.
• Only execute commands if the user has admin privileges.

Thanks for the PR @InternetRamen. :)

We don't want to import the functionalities through file reading. The handlers should detect the command and its args and use CommonJS modules to call the right methods.
