Add conditional formatting for color, marker and line to all types of charts

[Maxiglesias]

There's a limitation in color formatting for scatter, bar and line chart, in order to give de desired color to all visuals we have to go through a pain-staking proccess of clicking every single series of the given chart and type in the desired cod color. It would be fantastic if those unnecessary steps are simplified by a single conditional formatting workflow. Also it would be great to easily copy those formats between visuals in order to simplify further the process and make us focus in improving the storytelling of our dashboards.
