sparkler: parameterize particles
Having everything in fixed defines severely constrains the diversity of particle behaviors and appearances. This commit has been sitting around bitrotting since 2017, but now that there's all this settings infra. and randomizing via rtv, it seems worth landing, so I've rebased and am merging to prevent a bitrot->rebase recurrence. As-is, this commit ~minimally establishes a somewhat streamlined parameterizing mechanism w/X-Macro patterns, while wiring up a few of the obvious use cases surrounding xplode/burst, colorizing the default sparkler explosions while at it. It appears that when I first hacked this up I did some experimentation with parameters as well, so there are some tweaks to the behavior as opposed to a strict conversion of the fixed defines to parameters. They seem minor enough to just leave be. Plus a few minor optimizations like converting divides to multiplies were in there. Future commits can now wire up settings to choose from parameter presets for different sparklers...
