Add a chatlog feature to the EFU launcher

[Aethereal]

The launcher doesn't feature chatlog saving though does it?
That would be one suggestion from me.

<@Snoteye> It doesn't.
<@Snoteye> You can make a ticket and suggest that.

It would be nifty to have the EFU launcher support chatlogging similar to FleetingHeart's implementation.

Please. This would help me so much!

I never could get the chat logging to work -- I have to save my logs manually. I often forget. It would be wonderful if this could be added.
