Particle editor (#71110)
## About The Pull Request Demo: https://streamable.com/wnj3mf Features: - Full support for most gradients/vectors/numbers/generators/transforms ( I might have forgotten some of the more esoteric ones) - A "tutorial" section that explains the different rand/generation types and how physics works with pictures - Button for viewing what each var does - Selecting a particle type to set immediately - The generator types use defines now Not included: Color matrix support for color generators (I'm sorry but hell no) Special thanks to @jlsnow301 for explaining js things to me ## Why It's Good For The Game Making cool stuf ## Changelog 🆑 refactor: Added a particle editor to VV dropdown which can be used by coders and admins to edit particle values on the fly easily. /🆑 Co-authored-by: TiviPlus <572233640+TiviPlus@users.noreply.com>
