Set the default STATUSMSG to @ instead of @+ if it's missing

This fixes two issues:

- IRCNet doesn't have STATUSMSG, but it supports +channels, and
  including + in the default value meant processing those incorrectly

- The "bahamut hack", for old servers that support but don't advertise
  STATUSMSG, didn't work since ischannel_func doesn't use the default.

The choice of @ intentionally leaves out support for other STATUSMSG
(for example, AzzurraNet's bahamut 1.4 fork seemed to support + and % in
any order, contradicting the comment in the code).

I think this is a decent tradeoff, given how those servers are uncommon
and relying on +# or %# is even less common than @#.

Fixes #531
