Fix mocha integration - Fixes #369 #451

There is a single line change in the `src` file. I re-added a file that was deleted previously.

`BlanketReporter.prototype = OriginalReporter.prototype;`

Without this, blanket's reporter doesn't work with Mocha.

View with [spacing ignored](?w=1) to see the change clearly. The file looks like every line changed because it was in `dos` format so I converted it to `unix` format like the rest of the project.
