return of eventko

Recently had some time to rethink and rewrite Eventko - scraper for Ljubljana events. It is now officially a live as beta version. So far scraping venues that have events publicly posted on their websites. Will be adding more in the future.

Also rewrote the entire frontend web app - it is now a Progressive Web App (PWA), meaning that it can be saved to mobile phone desktop and be used in a headless browser mode - makes the UX a bit nicer, also adds caching and some other tiny improvements. Will be expanding it's functionalities as I go.

For now the service seems stable.
