- moved the visualisations plugins out

TODO:
1. the mpeg plugins need sorting out. currently they are all just placed inside
the main package. Need help with this since I am unsure about what files belongs where with what dependency
2. Cross-dependencies probably should be added to the plugins
3. License information should be added to the plugins
4. GStreamer-register needs to be added for each plugin
