Add Polar Charts and full axis support

[kMutagene]

This PR adds many things for #42 and #44 :

• Full support for the polar object on the chart layout
• Full Radial Axis coverage
• Full Angular Axis coverage
• Full Linear Axis coverage
• Unified Axis parameter casing
• All polar charts based on the plotly.js 2.0 spec (current ones are deprecated):
  • Logic to render scatterpolar derived traces via WegGL
  • Chart.ScatterPolar
  • Chart.PointPolar
  • Chart.LinePolar
  • Chart.SplinePolar
  • Chart.BubblePolar
  • Chart.BarPolar
• A fix on the title object. it now uses the correct, non-deprecated way to set any kind of title (a title object instead of just setting a string)
• Docs
• Tests

ScatterPolar derived traces with a few options set on the polar object:

[
    Chart.PointPolar(r,t,Name="PointPolar")
    Chart.LinePolar(r2,t,Name="LinePolar", ShowMarkers = true)
    Chart.SplinePolar(r3,t,Name="SplinePolar", ShowMarkers = true)
]
