Before we can show comments or versions inline, we need the groundwork to be done, which is the ability to display a list of events/activities inside a panel.

An event can be one of:

• file activity, as delivered by the activity list
• comments, as delivered by the comments component Adding comments to right sidebar for files & folders #16328
• versions, as delivered by the version app

The API needs to be generic enough for such apps to be able to embed their rows into the list.

I'll have a go at the generic interface/API on the Javascript side.

The question is whether we want a PHP-side API (app framework) that can deliver all events in one go or do we want each event type to be retrieved separately. Each approach has its own challenges.

@nickvergessen we probably need something similar to the activity manager where apps can push events. Or should we reuse the activity manager / activities as a base for all this ?
