* Unify the way we fork modules * Replace rollup-plugin-alias with our own plugin This does exactly what we need and doesn't suffer from https://github.com/rollup/rollup-plugin-alias/issues/34. * Move the new plugin to its own file * Rename variable for consistency I settled on calling them "forks" since we already have a different concept of "shims". * Move fork config into its own file
