0.20:
- As upstream became abandoned, created a ZBar fork at linuxtv.org
- Use libv4l2 for V4L2 support, using emulated formats as last resort
- Add support for Qt5
- Add zbarcam-qt and zbarcam-gtk (from the example codes)
- Add support for v4l2 controls
- Add the needed GUI bits for zbarcam-qt to work with controls
- Fix compilation issues with newer automake versions.
