Alert Server Changes - Event Rendering in Search

Our search page is currently not able to render nested fields. The event schema is using a nested structure for custom event fields. To improve the rendering of events on the search page, we might want to render events in a different way than we render regular messages.

This is not supposed to add full support for nested fields to the search page. If it's possible and not to much work, we could try to detect events and render them differently to show the nested data structure in a nice way. Apart from missing support for nested fields, the search page is also not showing fields that have empty values. For events the "key" field might be empty, but we still want to show it to the user.
