Update package.json: Remove warning upon install

The project was locked to requiring `"node": "0.x"`.

As there's no need to depend upon a very old version of Node, I've removed this requirement to solve the warning which always appears when installing:

    npm WARN engine ascii-table@0.0.8: wanted: {"node":"0.x"} (current: {"node":"5.4.0","npm":"3.3.12"})

I also bumped the version number to track this change.
