An error when global this is undefined

[gchudnov]

Noticed this issue when using Rx with Babel + Browserify and imporing Rx: import Rx from 'rx'.

The problem is here:

/src/core/internal/util.js:

  var inherits = this.inherits = Rx.internals.inherits = function (child, parent) {
    function __() { this.constructor = child; }
    __.prototype = parent.prototype;
    child.prototype = new __();
  };

this.inherits
^^
this might be undefined. It is set-up in /src/core/headers/outro.js as:

}.call(this));

And top-level this is remapped to undefined in Babel.

I fixed it locally by replacing }.call(this)); with }.call(this || {}));

And now I'm wondering if it is necessary to add inherits to the global this, polluting it?

Fixed as per commit and v3.0.1
