Remove Extraneous output filters in Sample Product Template

[fireproofsocks]

I really want our product template to be clean -- as you know, I dislike the use of if/then output filters in our templates, so stuff like

[[getProductImages:isequalto=``:then=`...

is not a great way to structure the template. Let's get the sample template working so it does not use output filters like this. We may need to adjust the actual snippets.
