Using GTK's GResources with GtkD with DUB

[WebFreak001]

I just want to push my blog again :p

You would want to use this for example when you make a GTK app 
that you want to add custom icons into. Using GResources will 
make it search your executable for the icon first.

Also this makes you not dependent on the filesystem for 
resources, everything is bundled in your executable.

There are also some hints and links how to use GTK4 and 
LibAdwaita if you didn't know yet.
