Make all components to work without Vue.config.replace = false

[noirbizarre]

Detailed Description

Vue 0.12 had a different behavior when instanciating components, it wasn't replacing the root element.
When migrating to Vue 1.x, we had to toggle Vue.config.replace = false in order to maintain a compatibility with some component.
This setting setting is deprecated and then removed in Vue 2.0.

Context

In order to stay close to standard Vue.js behavior, to allow upgrade and to simplify component styling (the component will be exactly as written, no custom surronding element), we need to drop Vue.config.replace = false and fix components for this behavior.
