Title: Add support for enabling or disabling smoothed lines in a scatter series

I noticed I was getting line smoothing even when a scatter chart's scatter style was set to a non-smoothed one. This change should set the correct defaults based on scatter style of the chart but also allows smoothing to be enabled or disabled on a per-series basis.

I also added tests for default smooth settings and overriding smooth settings.
