Some Vue components were already lazy-loaded, but not all.
There are three main changes:
1. Move init scripts outside Vue code.
2. Make the init scripts lazy-load the Vue components.
3. Deal with vue linters, because apparently if you do `export default` then some Vue linters will notice that's vue sfc.
The rationale for this pull requests is that this reduces the size of the `index.js` file.
