[www/seamonkey] Not possible to disable chatzilla

[Gary Palmer]

Hi,

My port config for www/seamonkey does not have the checkbox next to the
"Enable the Chatzilla IRC module" option set, and yet if I build seamonkey
chatzilla is included.  I believe this is due to chatzilla being moved to
being a "default" extension in recent versions of SeaMonkey.

Could the port be updated to handle the new state of affairs please?

Thanks,

Gary
