Update to Vaadin 8

[stevebor1]

Can you update this so it is compatible with 7, using Vaadin 8?

I did it in my fork, if you are still interested.

How do I get your fork?

[ilgun]

@jonasrotilli You have to get it locally and build it yourself for now. Can't remember if I released it on mvn central or not.
