Documentation: spam_modifies_subj

[Alan Munday]

A couple of notes about the README.sql-mysql readme (At least from the 
Fedroa rpm):

1 - In the example data section the deprecated spam_modifies_subj is 
still referenced.

INSERT INTO policy (id, policy_name,
   virus_lover, spam_lover, banned_files_lover, bad_header_lover,
   bypass_virus_checks, bypass_spam_checks,
   bypass_banned_checks, bypass_header_checks, spam_modifies_subj,
   spam_tag_level, spam_tag2_level, spam_kill_level) VALUES


2- A reference to drop spam_modifies_subj is missing (though it is 
included in README.sql-pg).

ALTER TABLE policy DROP COLUMN spam_modifies_subj ;
