Register widget shouldn't redirect to Register page on success

[pushred]

The Register widget currently reloads the registration page after it's successfully submitted. I currently have a check to send users back to the home page after this, but we should just do that by default. We should also offer a redirect parameter however for sites that may have a fan club's "home page" somewhere other than /.

You can specify the redirect url in one of two ways:

<div class="sparkart fanclub login" data-redirect="http://www.google.com"></div>

or

new sparkart.Fanclub( KEY, {
    redirect: {
        login: '/'
    }
});
