Feature: Adding semver ranges to the packages in the list

[mischah]

This would make it possible to define certain versions or version ranges as allowed/disallowed.

Specifying the version range should be optional.

Example list:

[
  "react",
  "react-dom@^2.2.1",
  "redux@>=1.0.0-rc.0 <1.0.1",
  "react-redux@^2 <2.2 || > 2.3"
]

I’m not sure about the combination between package name and semver range via the @? Any better ideas?

I think something like this is easier than having to use an array of object, right?

[
  {
    package: "react",
    versions: ""
  },
  {
    package: "react-dom",
    versions: ">2.1"
  }
]

I already had this feature in mind and would prefer the first option (array of strings).

I opened pull request #4 for this feature.

@mischah: Would be nice if you could throw an eye 👁️ on this 😉
