The GTK resource handling can now provide the path to resources rather than having to compute them separately. This reduces run time allocation and allows for the resources to be built in if required. Additionally this tweaks the resource scheme handling to redirect favicon.ico to resource:favicon.png instead of rewriting directly to file scheme path allowing the favicon to be a compiled in resource.
