Feature request: Different color for join and part messages

[94w9hrJJHqujXDFv]

I know I can configure message format in: Settings > Interface > Message format. But event (join/leave/etc.) messages are together. I like to see peope who join a channel in green, and people who leave in red. It would be great to have these event messages separated in two diffrent configurable formats.

Thanks for this app, all of you guys have made a very good job. I hope I can contribute to the source code in the future :D
