Use require("graceful-fs") if found instead of require("fs")

try {
  // optional dependency
  fs = require("graceful-fs")
} catch (er) {
  fs = require("fs")
}

See:

This would allow me to get rid of the graceful-fs dependency in my project and exclusively use fs-extra for my FS API.

This is a good idea, I'll look into it.
