* implemented the volume slider

* major speed and memory improvements to the image handling (the panel launches noticebly faster now) and controls 
* coding style fixes

- just FYI: The VLCFSVolumeSlider and VLCFSTimeSlider classes will be merged later on to add as little code duplication as possible.
