Update Vue.js implementation to use latest version & move from labs to first tab

0.11 is a big update which greatly improved internal stability.

Some reasons why I think Vue can be moved out of labs:
- Vue.js is now heavily being used in production at Optimizely
- There are large scale open source projects using Vue, e.g. https://github.com/mozillafordevelopment/webmaker-app
- It is also being actively used for creative development, with multiple sites winning FWA & Awwwards: https://github.com/yyx990803/vue/wiki/Projects-Using-Vue.js
- Included in jsfiddle's default list of frameworks
- Currently ~2.9k stars on GitHub

Also ran the tests against this update:
