This sets the default value for on-the-fly forum subscription.

(Also fixed a bug in postgres7.sql - a missing field for htmleditor!)
Now these are saved in a new table called course_display,
each user and each course can have independent settings.
I'm intending to expand this table later for all the other
course display stuff (like hidden topics etc)
Course creators are managed by /admin/creator.php , same way that admins.
Or if authetication module have 'auth_iscreator'-function (right now only ldap-module have) ,
users are added to creators at login time.
Moodle tables.
ie user -> userid in many tables, plus in user_students
start -> starttime and end -> endtime
I've just done all this as carefully as I could ... I don't think
I missed anything but it's pretty intensive work and I'd be fooling myself
if I didn't think I'd missed a couple.
Note that this version should pretty much be able to bootstrap itself
using PostgreSQL now ... but this is untested
