Summary:
When browing through flipper one gets random warnings about uncached icons. Since we can't predict which plugins use which icons, it is hard to keep the list in `icons.js` updated.
This diff extracts the table to a separate json file (static/icons.json) and if an icon is missing in development, it will automatically add it to the list, so that the icons will be part of the prefetch of the next build / restart
