Show current URL in session recording, allow jumping to when page was visited.

Is your feature request related to a problem?

When looking at session recordings, you often want to jump to the 'interesting parts'.

Describe the solution you'd like

One way to do that is:

1. Show page url in session recording
2. Show notches in the replay bar when page changes happen
3. Provide a timeline in the sidebar, allow jumping to specific events
