This avoids every page on the site parsing 250KB of JavaScript.
supporter-page.js isn't the most elegant code, but at least it's a little more
modular now and no longer user jQuery.
The fundgoal section is now always included, but an if statement now
wraps the entire (partial) file, which will only generate any content
if it's not more than one week after the fundraiser has ended.
Add an else that indicates these are results if it is past the end of
the fundraiser.
