#192 Services: Prevent entrymsgs from spamming warnings

[Valentin Lorentz]

Hi,

This is a patch from a Limnoria contributor. I don't remember the details, but it looks like on some networks, ChanServ sends a notice to all users joining a channel formatted like "[#channel] Welcome to our channel".
These patches disable warning in the console for this kind of messages.
