[UI] Create events page

The idea is to have a page similar (but preferrably UI-richer) to the old one: https://jug.bg/%D1%81%D1%8A%D0%B1%D0%B8%D1%82%D0%B8%D1%8F/

Almost done, maybe in the "event" when we open the full details we should include google maps.

Similar how we do it for http://java.beer basically it is just an embedded map with query q= location
