Added support for specifying referenced fonts per renderer in addition to the general match list. If any of the two match lists (if specified) match a font, it is not embedded.
* Extracted business logic from PrintRendererConfigurator and created a new FontDetector and FontAdder in org.apache.fop.fonts package.
* Created a new FontInfoConfigurator that factors out a lot of the static stuff in PrintRendererConfigurator.
* PDFDocumentGraphics2DConfigurator now uses a new FontInfoConfigurator() instead of static PrintRendererConfigurator.buildFontListFromConfiguration() call.
* static method updateReferencedFonts() in PrintRendererConfigurator moved to an instance method in FontManager.
