swap placehold.it with holder.js from bootstrap

[dillongreen]

Is there a particular reason placehold.it is used instead of the built-in holder.js with bootstrap 3?

Not having to rely on some external URL such as placehold.it would be easier to configure with regards to frameworks like Meteor that provide support for setting the same-origin policy.

I like placehold.it because it uses the standard image source tags rather than a data target. That way it is easier for someone who downloads the template to just plop in their image where the images are supposed to be.
