Task 4: Use discord.ext.commands to make a better bot

[JayDwee]

Describe the solution you'd like

1. Create your ping command using ! as a command prefix (see slide 14)
2. Create a command that says hello to you using your provided name (command: !hi Jack --> bot replies:hello Jack!)
3. If a name isn't provided use the senders discord tag (e.g. !hi --> hello JayDwee!)
4. Use slide 16 to help make a command that responds with the number of arguments provided, as well as returning them sorted in alphabetical order
5. Split some of your commands into separate cogs (docs)

(for Monday)
When task 4 is completed move on to this:

• Clone the KoalaBot repo locally
• Add your own bot token to the .env file as explained in the README.md file
• Run KoalaBot (ensuring your previous bot is not running)
• Follow the readme and try running our tests (without some API keys some of these tests will fail, but most should pass)
• Spend the rest of the day playing around and getting familiar with Koala and its many features

If you get stuck look at the README.md and CONTRIBUTING.md files
