Started implementation of Video Chat (not working yet!).

- GUI part is done
- implemented a very basic JPEG codec
- added echo frame in configuration panel
- created a video capture object that uses OpenCV (should be cross systems)
Remains to do:
- serialise and send frames through p3VoRS
- use a serious codec (e.g. Theora+x264)
- add icons to reflect camera state (failure/working/sending/...)
- compilation on windows
