test(integration): make em at least run locally

This commit does a lot but it's all connected and tries to make everything more extensible and future proof.

1. CLI arguments and options from the "package.json" are no longer treated as two different things. You can now pass options either way.

BREAKING CHANGE: cli arguments are now normalized to camelCase, so e.g. `options['github-url']` is now `options.githubUrl`

2. Plugins no longer receive config they need one by one, but in one huge object. This way it's easier to pass more info in the future w/o breaking existing plugins that rely on the position of the callback in the arguments array.

BREAKING CHANGE: Plugins now need to read their passed options from one huge config object.

Old:
```js
module.exports = function (pluginConfig, foo, bar, cb) {…}
```

New:
```js
// ES5
module.exports = function(pluginConfig, config, cb) {
  var foo = config.foo
  var bar = config.bar
  …
}

// ES6
module.exports = function (pluginConfig, {foo, bar}, cb) {…}
```

+## What is `semantic-release` about?
 
-`semantic-release` provides "prepublish" and "postpublish" hooks so you automatically release the correct version.
+At its core `semantic-release` is a set of conventions that gives you entirely automated, semver-compliant package publishing. _Coincidentally_ these conventions make sense on their own, like having meaningful commit messages.
 
-Run `semantic-release pre` right before `npm publish` and `semantic-release post` right after. 
+[![JSConfBP Talk](https://cloud.githubusercontent.com/assets/908178/8032541/e9bf6300-0dd6-11e5-92c9-8a39211368af.png)](https://www.youtube.com/watch?v=tc2UgG5L7WM&index=6&list=PLFZ5NyC0xHDaaTy6tY9p0C0jd_rRRl5Zm)
 
-The post hook is automatable in `package.json` with a "postpublish" script:
-```json
-"scripts": {
-  "postpublish": "semantic-release post"
-}
-```
+> This talk gives you a complete introduction to the underlying concepts
 
-This is currently not possible for the "prepublish" hook. See [npm/npm#7118](https://github.com/npm/npm/issues/7118).

+The next branch is a completely rewritten version of `semantic-release`, that isn't fully tested and documented yet.
+It has lots and lots of great new features, but also breaks a lot of things.
+Unless you're adventurous you should look at the [stable master branch](https://github.com/semantic-release/semantic-release/tree/master).
