Add support for wildcards in excluded folders

I recently moved from "back in time" to Déjà Dup and I'm quite happy with this decision, however there is one feature that I'm missing.
In back in time I could choose the folders to exclude from backup also by wildcards, so for example selecting ~/.wine* excluded all the wine prefixes I have in my home folder. Since I often create new prefixes it was a really useful feature.
I hope you will consider to add this feature...it would be great!
Thanks for the awesome software by the way!
