title: Set v-switch to be on, with value: 'false' (invert value with v-model)
body: <p>I have a <code>v-switch</code> that I'd like to be "on/true" so that the switch is to the right, but still have the v-model value to be "false", and then when the switch is "off/false" have the v-model value to be "true", essentially inverting the values.</p>
  
  <p>I'm struggling to find this an option or how to do this. I'm using Vuetify 1.5.15:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;v-switch color="success" prepend-icon="notifications_off" v-model="url.muteNotifications" @click.capture.prevent.stop="togglePolling(url, urlNo)"&gt;&lt;/v-switch&gt;
  </code></pre>
