Support File Loader

[pl12133]

Users of css-loader have become accustomed to having url('...') statements processed by url-loader and file-loader. This loader should emit fonts and images in the same exact way that css-loader does.

I have had no luck on finding documentation on the topic of a loader requiring other files in the way css-loader does. It seems that css-loader injects a runtime to require all the assets from url() statements, but I have yet to find a viable solution.
