Initial version of GResource

GResource is a bundle of files combined into a single binary blog.
The API lets you access the files the resource contains by
using resource paths. You can also register resources with a
global list and access these globally in a merged resource namespace.

The normal way this is used is to link in the resources into your
application/library and have it be automatically registred.

Resources are compiled from an xml description using
glib-compile-resources.
