making mojito to work on windows

## Goal

* To support windows "partially" (which means, all unit tests and basic features tested, but not functional tests)
* To drop support for `nodejs@0.6` because that version does not support windows
## Steps to verify

With this commit very first commit, we get a dummy app working on windows, yay!

```
npm i mojito -g
mojito create app foo
cd foo
mojito create mojit bar
mojito start
```

then navigate to `http://localhost:8666/@bar/index`

## TODO

 * [x] Test simple server side app
 * [x] Test simple app with `HTMLFrameMojit` deployed to the client
 * [x] Test `mojito test app .` in a simple app
 * [x] Test rpc calls thru the tunnel (common example)
 * [x] Unit tests to pass
