Group netsplits and group rejoins (and only play one sound per group)

[tick]

If netsplits and large amounts of joins at the same time could be grouped onto the same line, might be nice.

One thing I've seen in logs from other clients is to detect netplits by the quit message and merge all the resulting PARTs into a single log message, something like this:

[12:30pm] Netsplit *.net <-> *.split quits: nick1, nick2, nick3

Detecting netsplits is quite easy; it's simply two space-separated server names (though I know one network uses dummy server names such as "*.net" or "*.split" rather than showing the real server names) in a quit message. I'd say that nearly any quit message not containing a colon is probably a netsplit (unless it's "Client Quit" or "Remote host closed the connection" or something), though I don't know enough about quit messages to be certain.
