Implement folding sections for multiple consecutive state events. This also reworks some of the aggregated text output: - Only new days cause a new section - The aggregated text starts with either a single username or n users - If the same user did the same action mutltiple times it will be in the aggregated text a user did x n times - When there are multiple authors in a block with multiple state event types it will use or rather than and before the last event. e.g 3 user left the room or joined the room.
