Dave Ward a166add97f 3rd Party Service admin (OpenOffice, SWFTools, ImageMagick)
- All supporting classes moved out to thirdparty subsystem
- Open Office service automatically started if available
- All utility locations editable via JMX (and subsystem can be reinitialized with new values without rebooting tomcat)
- New ContentTransformerWorker interface introduced in order to allow separation between ContentTransformer registry and third party utilities
- Existing JMX query capabilities preserved
