Override Tab, Bookmarks, History Support

[shaydoc]

I created a local branch for override support, would be good to integrate this in

  if (options.components.override) {
    api.render('./template/override', { name, ...options })

    pkg.vue.pages['override/override'] = {
      entry: 'src/override/override.js',
      title: 'Override'
    }
  }

 <%_ if (options.components.override) { -%>
  "chrome_url_overrides": {
      "<%- options.components.overrideOption || 'newtab' %>": "override/override.html"
    }
  <%_
  } -%>
