Fix invalid package

This fixes #6 which prevented `README.md` from being rendered in [npmjs.org](http://www.npmjs.org) and instead displayed `ERROR: No README data found!`

The main issue was the repository line which should be defined like this:

```json
{
  "repository": {
    "type": "git",
    "url": "git://github.com/icflorescu/aspax.git"
  }
}
```

For a better insight into the added changes or to fix the other repos, take a look at the `package.json`.
There's also this [validator-npm](https://github.com/gorillamania/package.json-validator) and [web](http://package-json-validator.com/) that can help you validate your package.json files

If you run into problems trying to publish to npm you could try running `npm publish --force` as a last resort. Let me know if you need any assistance.

Finally, I also went ahead and added a version badge to the README :ghost:
