The log was trimmed to 50 lines, which isn't enough to scroll back
through a conversation - now 250. Chat entries also carry the time they
arrived, shown as a dimmed HH:MM in front of the name, behind a new
"Show timestamps in chat" setting.
The timestamp is kept next to the text rather than baked into it, since
the chat view finds the sender by splitting the line at the first colon.
Fixes#15444
