add percentage to quantities

[carlotta-93]

Hi,
First of all, thank you very much for this great package!
I was wondering if it would be easy and/or useful to have the percentage printed as well as the numbers of elements in each set.
Something maybe similar to the print.mode = c("raw", "percent") (from the VennDiagram package), to be added as parameter.
So that the output would look like this:

I second this :)

Is there any hack to make this work?
