Remove Item From Cart

- The user can now remove an item from his/her cart
- The HTML form generated by './cart.php' now has an id;
'#removeCartForm'
- '.js/mylibs/lacy.lib.js' now attaches an event handler to all HTML
forms with id='#removeCartForm'; performs AJAX call to
'./php/cart/ajax/cart_remove_item.php' when submit event is fired
Changed Include Order

- './cart.php' now includes './header.php' first
- './header.php' now includes other files AFTER it has started the
session
- Created './test/phpinfo.php'; can be run to view information about
your PHP version
