NEW: the option to redirect the button with a link for each package to any website where payment is subsequently made (e.g. directly to PayPal or any other payment processor). Note: this is not automated, you must enter the URL where the button redirects you to. By default, it points to the user account upgrades page.
removed links from some of the elements for each package (there were too many). Now there is only a button linking to the payment process.
