Don't group timeline items if more than 5 minutes has passed.

[pixlwave]

This PR slightly tweaks the grouping algorithm so that we split up the bubble groups if more than 5-minutes has passed between messages from the same sender. I'm sure there could be lots more done here (such as splitting up groups if they span a long continuous time) but this seems like a simple start to make it easy to visualise the passage of time (and frankly fix something that really bothers me day to day).

The behaviour appears to match Element Web from my testing.
