Minor changes - gateway events

A small addition to the methods on the data object, allowing users to catch-all gateway events.

I also clarified the related example a bit on the readme.

v1.0.2 - ES2015 transpiling as default

This release comes with a transpiled version of the library as its default export (index.js). This default export is therefore accessible to anybody running nodeJS > 6.x, as defined in the transpiler config.

Users wishing to use the ES7-featured library directly (and transpile on their own, if needed) can import src/index.js instead.

v1.0.1 release

This release contains a stable LORIOT connector for both websocket & REST APIs available on all backoffices.
