ADG v.0.3.0 released

Automatic Drawing Generation is GObject-based library that provides a non-interactive Cairo canvas specifically designed for generating technical drawings.

http://downloads.sourceforge.net/adg/adg-0.3.0.tar.bz2

Reworked styles and implemented AdgContext, a clean and well defined approach to manage rendering customization.

Moved all the geometrical stuff in Cairo Path Manipulation Library (CPML), an internal library depending only on cairo.

Greatly improved the documentation.
