Merge pull request #1481 from futekov/patch-1

Update for Readme.md

Move test runner out of make

* Make does not come on windows (by default)
* We were doing nothing special with the make file for the tests
* Putting the mocha command inside of npm test is SUPER portable
* Attaching tools like node-debug while running the tests is now as simple as node-debug npm test
