Re: GTK 3.20 Nim wrapper

Stefan, do I really need -dev package?) Yes they're separate, but as I did not 
had to install GTK2 and GTK3 dev packages, I thought, that I will not have to 
install it. I'll make this in the near time (now I'm working with my teammate 
on game under UPBGE), after I'll correct some errors - I'll do this.
