adding Sadarghat popover to homepage

[Check it out!](http://iuloshi.github.io/new-market-goods/) Closes #61.

* Made the product detail background color Wes Anderson red, but obvs feel free to change. :stuck_out_tongue_winking_eye:  
* Also I set the responsive breakpoint for the images to become full width again at 960px. We could easily make that smaller though...I feel like users could still scroll horizontally at that viewport width. Whatcha think @ohsk?
