Engine:

• add anim/play: This node offers a better control than the anim/null, as in it takes in the timelines from 2 nodes, one allowing to set the objects to their initial state, and one where the animation should go to. On top of that, it offers a seek parameter, which allows to scrub through the animation. This is very useful when dealing with complex or long animations.
• anim/propertyValue: add color param.
• gl/constant: add color param, which generates the same glsl as a vec3, but has a color html input for a better control.
• gl/subnet: The inputs and outputs of the subnet are not defined anymore by plugging nodes into it, as this made other actions like collapsing nodes into a subnet difficult. It also was tricky to move inputs around. Now, the inputs and outputs are defined by parameters. This changes also affect the gl/ifThen and gl/forLoop.
• materials and textures: improve system to update material textures when a COP node changes
• sop/palette: rename the .palette integer param to .paletteName string param.
