no whois/ison/watch for server notices and services

[jane]

as of r4019 the notifications also include whois/ison/watch etc. for services and server notices sent to the user when "show notices as private chat" is enabled.

for server notices, no valid response is received from the server so the list item is greyed out as though the server was a user that was offline.

for services, while a notification could be useful when the user is manually typing commands, there isn't really a need to watch or whois services when it's a notification for something performed on connect that the user would not have manually typed, i.e. identifying with NickServ.

if i'm not mistaken all that remains to do here is remove the online check for server notices. tim disabled whoising and notices from services dont show up during connect if youre using default prefs :)
