Replacement of socket.io as the server-transport with websockets using WS 

This is a replacement of socket.io as the server-transport with websockets using WS instead.

Should be fixing #290 and #274.

#### Consequences:
- Re-gained compatibility with Chrome DevTools.
-  Re-gained compatibility with current version of the RemoteDebug protocol.

#### Potential enhancements:
- There should probably be added a few tests to test the connection itself.

#### Tests:
- Tested in Chrome 32.
- All unit tests are passing.
