[New build - EXPERIMENTAL] 21w24a: RGB controller gate

A new RGB controller gate has been added to the brick roaster.
Use it to control the color and brightness over time on light and glow bricks.

Feature:

• Up to 4 colors
  
• duration tweak
  
• gain tweak: a higher gain will spend more time on the color and less inside transition.
  
• Loop or Ping pong.
  
• You can set the controller to be active or not with a simple switch.
  
• For now colors are RGB input, but a color wheel will be added.
  

This build also introduced some big change on the command system behind the scene.
This allows leveraging on the new data-oriented performance stack and will be used extensively in upcoming updates.

Bugfixes:

• #3860 Game breaks on Quit To Title
  

Thanks for playing!
