Usernames

[Bake-Ware]

As a user, I'd like to have a username and see other people's usernames in the chat

Until we get users and registration setup, I'd suggest letting the user just set a username then save it to a cookie. Then have the cookie get read when the user opens the page.

Another option is using local storage to do this.

Added some placeholder logic for this just to make the chat compliant with the external chat versions (cmd and winforms)
