dots in boxplots shouldn't be covered by background color

[StephanDecker]

There came up a generell issue with the chartjs boxplots library.
The dots of the boxplots aren't properly visible. We played around with the alpha value of the background color, but still it's not very nice.
Couldn't the dots be brought to the front of the boxplots?
In some cases with few samples we want to show the dots within the boxes. That is supported by the boxplot chartjs-lib and has already been implemented for some views. You can show the dots by the following setting (see also the code snippet above).
itemRadius: 3, // render items
