The results of Guy Bedford's help

Egroupware will load into addressbook & show rows
Most base files should be bundled server-side & included
rollup.config.js controls the process

- consider /dist directory for best-practice
- cleanup
- other built-in apps
- EPL / external apps need Guy's multi-stage work
