This commit removes babel/es6 from all source and test files, because it was introducing a lot of overhead and only little gain.
This commit fixes and enables integration tests on Travis.
This commit fixes#153 and #151 along the way.
_Originally this commit should have only removed babel, but without working tests that's a bit too hairy._
_I only realized that half way into removing babel/es6, so things are all over the place now._
Closes#153, Closes#151
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) {…}
```
