users.sql: Updated database schema; split subject and offering tables.

Need to manually apply the following commands to being the database up to
date. Note that this will wipe all data in your "offering" table - which
shouldn't matter because IVLE has never used this table to date.

CREATE TABLE subject (                                                               
    subjectid       SERIAL PRIMARY KEY NOT NULL,
    subj_code       VARCHAR UNIQUE NOT NULL,
    subj_name       VARCHAR NOT NULL,
    subj_short_name VARCHAR,    -- may be null
    url             VARCHAR
);

DELETE FROM offering;
ALTER TABLE offering DROP COLUMN subj_code;
ALTER TABLE offering DROP COLUMN subj_name;
ALTER TABLE offering DROP COLUMN url;
ALTER TABLE offering ADD COLUMN subject
    INT4 REFERENCES subject (subjectid) NOT NULL;
