Title: Swap image source based on breakpoint

* Looks for image pattern ```file_768.jpg``` to replace
* Image must have ```class="wdn_image_swap```
* Works on page load and page resize
* Doesn't require jQuery

Thoughts/Concerns
* Not tested in all browsers (just OSX Chrome)
* Not sure if 1040 is really needed, as the main content only goes to 960
* If an image isn't found, should it try to find the next largest to use (i.e., 320 was used but page rendered at 960. Currently it will simply keep the 320)
