Revision 756522

A little font configuration cleaning.

* 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.
