Code in this was migrated to cookieHandler.js
Minor script linking changes; integrated cookie system

Also did a bit of code formatting.
Integrated cookie system

integrated my cookie system, no display's yet but the cookies ARE
working
Migrated code from intro.js which was removed

Handles all the cookie stuff. Will most likely expand at some point, use
the checkCookies() function in your games and change the href as needed
