Reduce irc spam/information leak

[Frotty]

The bot shows registered email addressed upon sign in:
[WHISPER: europe.battle.net] [# Email Service #] Note: Email on record is [[email protected]]
Which it shouldn't imo.
Then it also prints every dis/connect message like so:

[06 Dez 17 01:04] * OxBot: [BNET: asia.battle.net] disconnected from battle.net due to socket error
[06 Dez 17 01:08] * OxBot: [BNET: useast.battle.net] connected
[06 Dez 17 01:08] * OxBot: [BNET: useast.battle.net] disconnected from battle.net
[06 Dez 17 01:08] * OxBot: [BNET: asia.battle.net] connected
[06 Dez 17 01:08] * OxBot: [BNET: asia.battle.net] disconnected from battle.net

Which is not useful either. It should be completely removed imo, and just have a warning when someone hosts and the bot is not connected to all realms.

You remember yourself, that my bot was spamming channel 007 and you therefore banned him.
