A commit after a long time

[Andreas Zehender]

Hi Luis (and all)!

I've just committed the next step for the plugin framework:
- Support for custom formats and serialization methods
- Plugins can register new formats and add serialization methods for objects
- Custom import/export file dialog that handles all registered formats
- Objects only contain serialization methods for the KPovModeler xml code, the 
povray serialization methods are now in the file povray31serialization.*
- The serialization methods can report errors and warnings

Please tell me any object (with attribute values) or object hierarchies that 
can produce a povray error.

For example: An empty texture is exported by KPovModeler without any warning, 
but POV-Ray returns with an error when rendering the scene.

Greetings, Andreas
