Plugins + Scripts VideoBiasLight - Dynamic Light That Reacts to Videos

- Added the ability to switch between a spotlight and point light.
- made sampling center weighted like a real tv

While the point light gives a more realistic glow, the spotlight might come in handy for some in certain scenarios.

- Fixed bugs that caused the light to stay in the scene when the plug-in was disabled, or image panel removed by properly parenting the light to the panel
- various other fixes to improve performance

- sampling was actually broken in last version due to bad code, fixed it and whole image is sampled
- point light moved slightly forward to get rid of light behind panel
- ability to disable shadows which can greatly increase performance if the light from the screen overlaps with a VAM light
- saturation setting, can increase/decrease saturation (you will not see immediate results, the scene in the video needs to change color enough to trigger the update)
- contrast setting, can increase/decrease contrast (you will not see immediate results, the scene in the video needs to change color enough to trigger the update)
- plug-in is now better behaved, checking and unchecking it will clear light and resources properly
