Release fixes for descriptive stats

I think there is no real reason not to draw the rugs even for discrete data, if the user wishes to do that...

I am not sure about the scaling of the plot; tbh a lot of plots in the module seem to me as unnecessarily gigantic, was that a deliberate choice, @JTPetter?

@Kucharssim Okay, I didn't see a purpose for rugs for a barplot but sure, if anyone wants it :)

With regard to the plot sizes, it was a deliberate choice for many plots, yes. There are a lot of annotations and other layers over most plots, so I used the geom_fixed coordinate system, so I have more control over where everything is placed. However, with geom_fixed the plots can get really big if there are a lot of data. This is mostly relevant for the dotplot, which will otherwise dynamically change the dot sizes, which looks really bad with small numbers of dots. I currently don't have a better idea how to handle this...
