v0.14.0 no longer scales down background images

[rbirkby]

In v0.13, the background image is scaled down (the image is 1800x1350):

In v0.14.0, the background image is not scaled:

A workaround is .remark-slide-content {background-size: cover}

Code:

    <textarea id="source">
layout: true
background-image: url(arghh.jpg)

---

# Slide 1
    </textarea>

I just found the same issue. It might be related to #307. We can set the background-size property for individual slides now, but I think background-size: cover is a better default.

I hit it too :(
I changed background-size: cover to background-size: contain to fix it locally.
