title: Meta tags doesn't work with Vue-router
body: <p>I'm using Vue webpack template: <code>vue init webpack router-app</code></p>
  
  <p>Setting meta titles in "router-app/src/router/index.js":</p>
  
  <pre><code>export default new Router({
    mode: 'history',
    routes: [
      {
        path: '*',
        component: NotFoundComponent
      },
      {
        path: '/',
        name: 'LoginPage',
        meta: { title: 'Home', bodyClass: 'dashboard' },
        component: LoginPage
      }
    ]
  })
  </code></pre>
  
  <p>LoginPage.vue:</p>
  
  <pre><code>&lt;template&gt;
    &lt;form&gt;
    ...
    &lt;/form&gt;
  &lt;/template&gt;
  
  &lt;script&gt;
  export default {
    name: 'LoginPage',
    data () {
      return {
        msg: 'Login Page'
      }
    }
  }
  &lt;/script&gt;
  </code></pre>
  
  <p>But it doesn't affect my meta title at all. In a vue dev-tools (Chrome) i can see that <code>$route</code> has my meta tags.</p>
