[Mailmunge] 3.08 change to $ctx->METHOD(@args);

[list at ptld.com]

The functions such as filter_recipient() and filter_message() capture $self.
     my ($self, $ctx) = @_;

$self was only used in $self->METHOD($ctx, @args) which is now $ctx->METHOD(@args);
After making these edits $self is no longer needed and only exist in the function capture.

I assume i need to keep that "dead code" due to ordering of what is passed to the functions.
Any plans on this? Will it be removed someday? Anyway to remove it now?
