Refactor and use dush (v2)

[tunnckoCore]

Make it not rely on this and use the dush as core event emitter

[tunnckoCore]

Need updates to minibase-is-registered and dush-promise plugins.
And probably update minibase-create-plugin

• supports named plugins with .use('foobar', pluginFn) or .use(function foobar () {})
• supports unnamed plugins .use((app) => {})
• works on node 0.10 if options.Promise is passed or if ANY promise is detected in deps
• never throws, emit error event and also can app.catch() errors
• has .use, .on, .off, .once and .emit methods through dush
• has .isRegistered through minibase-is-registered
• has .then, .catch, .resolve and .reject through dush-promise
• has .define and .delegate methods through dush-methods from minibase-is-registered
