Bump for next version
chore(): add bower into npm's post-install cmdlet
chore(): breaking chance regardings setup, configuration, options

Before this commit, all relevant options were injected directly which
could conflict with other modules's namespaces.

Starting now, all options have been moved into a dedicated options object
`angularVertxBusOptions` which MAY be injected or modified. However, the
new module provider `vertxEventBus` provides shortcuts to all options.

For instance:
```javascript
var app = angular.module('app', ['knalli.vertx-eventbus']
.config(function(vertxEventBus){
  vertxEventBus.useDebug(true).useUrlPath('/eventbus');
});
```
