Ergonomic enhancements for AudioFileProcessor plugin (interactive wave view).

Browse Source 
This patch includes:
* sampleBuffer::visualise(): add possibility to specified a range to visualize instead of the whole sample
* add sampleBuffer::sampleRate() and sampleBuffer::sampleLength() getters
* definition of AudioFileProcessorWaveView and AudioFileProcessorWaveView::knob classes for AudioFileProcessor plugin
* knob::getValue() specified “virtual” to allow redefinition in child class  AudioFileProcessorWaveView::knob
* delete audioFileKnob class (made obsolete by AudioFileProcessorWaveView::knob)
* add audioFileProcessor::isPlaying() signal, which is emitted in audioFileProcessor::playNote
* change type of AudioFileProcessorView::m_startKnob and AudioFileProcessorView::m_endKnob (AudioFileProcessorWaveView::knob instead of audioFileKnob)
* replace AudioFileProcessorView::m_graph (QPixmap) by AudioFileProcessorView::m_waveView (AudioFileProcessorWaveView)
