Add account into ban owner info

When an unauthed client sets a ban, nick is saved as owner of the ban,
when the client is authed, account.users.quakenet.org is saved.

This should not break clients as servernames can (and did appear there
in asuka) and probably appear there in other IRCDs. Forcing a nick!user@host
format seems odd, *!*@account.users.quakenet.org seems a bit ugly, and saving
the nick and user part too costs even more and adds little, account is the most
significant piece of info there already.

What about a channel service like Q:
Should we then save Q.users.quakenet.org, or simply stick to Q
Q, or rather in general, a channel service normally does not change nicks?
and since Q does set quite a lot of bans (and topics), this might save a bit on bandwidth.
