Features

• Silent/Loud splits are now preserved in clip/chunk form. Closes #288
• Audio time stretching is now done with ffmpeg's 'atempo' audio filter instead of the python phasevocoder. This changes makes time stretching faster and the audio nicer sounding.
• Rewrote audio rendering so that:
  • de-syncing from timeline is guaranteed not to happen
  • overlapping audio clips are mixed
• All visual objects now have the rotate, stroke and strokecolor attribute
• Video timebase is set to 1/fps if fps is an integer, may help with #281
• Fix --preview giving incorrect clip/cut info
