Version 1.0.0-alpha1

Compatibility with upcoming Chart.js 2.0

There are numerous breaking changes in this version notably:

• all options now need to use the chart- prefix
• chart-colours is now chart-colors and chart-get-colour is now chart-get-color
• chart types are in camelCase e.g. line and polarArea
• legend is now a Chart.js option so the chart-legend attribute has been removed
• events emitted on creation and update are now prefixed with chart- e.g. chart-create
• obviously all Chart.js breaking changes as well in how options are set, etc.
