If `template` option is an actual template node, auto use its `content`.

@yyx990803 Can you give an example in how it should behave? AFAIU this will remove the need to do things like:

Vue.extend({
  template: $('#my-thing-template').text()
});

Am I right?

Well, currently the template option accepts three things:

1. a template string
2. an id selector of the template node (either a <script> node or a native <template> node)
3. a DocumentFragment.

So you can already do:

Vue.extend({
  template: '#my-thing-template'
})

This fix is intended to make this possible:

Vue.extend({
    template: document.querySelector('template') // a <script> or <template> node
})

As for your example, it removes the need to call the extra text().
