added plugin_path property to plugin object in python
audio is now clamped instead of wrapped around in audiomix and audiogain, these functions can also now warn when clipping happens
the vfw wrapper now provides simple waveformatex information automatically if the audio is mono or flagged as plain stereo and samples contain no padding bits
