Change name of the render method to ensure compatiblity with Vue 2.0

[LinusBorg]

Vue 2.0 introduces its own render() function which allows to render vdom elements programatically (like Reactjs).

This will conflict with the render() method of this lib.

to ensure compatibility, a breaking change is required - renaming this method to something else, e.g. renderChart()

Good point. There are also a few other points that needs to get changed to be fully compatible with vue 2

[LinusBorg]

There sure are.

Working on it in the next branch.
Seems to be working for now, but needs more testing :)

Will look into how to handle multiple releases, so people who are using vue 2.0 can use it, too.

It is now installable over npm i vue-chartjs@next
