Fix: Aphrodite UI enhancements

* New: Display UI before movies have loaded

* Revised webpack bundling

* New: Option for production build with profiling

* Fixed: Faster hasDifferentItems and specialized OrOrder version

* Fixed: Faster movie selector

* Fixed: Speed up release processing, add indices (migration 161)

* Fixed: Use a worker for UI fuzzy search

* Fixed: Don't loop over all movies if we know none selected

* Fixed: Strip UrlBase from UI events before sending to sentry

Should mean that source maps are picked up correctly.

* Better selection of jump bar items

Show first, last and most common items

* Fixed: Don't repeatedly re-render cells

* Rework Movie Index and virtualTable

* Corresponding improvements for AddListMovie and ImportMovie
