* How it does it:
* Checks if there is a cookie present. Gets username and password that

* and password. [We can't use connect.php right now since there is no
* cookie at all] It then validates the user. We get the MySQL time
* and make a new cookie.
*
* Check if there is a cookie now. If there is verify the user. [Sometimes
* there will be no cookie created straight away so we have to make it so
* the user can log in with a cookie or no cookie in this page]
* Get the users information and print that out to a table.
*
* Check how many people are online right now. Check if user is on the
* list. If they are not then add them to the users that are online and
* print the users that are online. If user is alreadly on list then
* just print the list.
