Parse memes at runtime?

[Roy-Orbison]

This is a feature request to make the plugin code and meme resources modular. Then server admins could add or edit memes any time without having to have them officially included via a PR, or set up a dev environment to recompile from a fork. The plugin could scan files on (re)activation, include valid ones, and log errors for invalid ones.

I also thought JSON metadata might be friendlier for this. Golang projects seem to use it fairly universally, it's more widely known, and has fewer pitfalls than YAML.
