Combo line & bar, upgrade chartjs to 2.0

[jamding]

Chartjs 2.0 introduces combo line & point, requires upgrading chartjs dependency and exporting react component

[benmccann]

Depends on #84

hey @benmccann, I saw you making some merges to chartjs-v2 branch.

Why don't we just work on that branch, release as the version you've specified for now while we test it in beta - 2.0.0-beta2 ?

I think once we're ready we can just release react-chartjs as 2.0.0 with Chartjs 2.0.

@benmccann and @jamding I am going to go through what we have in our issues and label as version 2.0.0 for features needed for Chart.js 2.0.

We are on version 2.7.0 of chartjs and react-chartjs-2 so what is the status of doing a combo line & bar chart?
