incompatibility ES6 +

[navarrojava]

When I use es6 feature "destructing assignment", the variables do not work.

// It does not work
const { MY_VARIABLE } = process.env;

// It work
const MY_VARIABLE = process.env.MY_VARIABLE;

I think a little tuning in the engine that extracts the variables can fix it.

I would suggest you refer to this comment: #70 (comment)

We have done extensive research and it actually is fully supportive with es6, however the way that webpack.DefinePlugin works.

We can either leak all process.env variables every time you reference a single variable, or we can remove the ability to destruct your env variables. For the purposes of security we opted to use the former.

I am closing this as it is a duplicate of #70. Let me know if there is anything else.
