Voting feature

When a product is "coming soon", a voting form is added under the label, allowing visitors to vote for the products they want the most.

The admins can then see in the dashboard which products are most wanted and prioritize the development of new products. A count of the votes is also available on each product page, right under the "Coming soon" checkbox.
In my (limited) experience template_redirect is generally fine. If you're up for building ajax submission we won't need this, otherwise it's good for 1.3 :) I can add ajax at a later point so we can keep them in the same location when submitting vote.
