- Redid settings.module and even renamed it to conf.module.
* Settings are now grouped in basic categories like "system
settings", "module settings" and "filters".
* Added new settings to make Drupal easier to configure and
to make some aspects like the watchdog scale better.
- Renamed includes/settings.php to includes/conf.php.
- Added filter support to conf.module and introduced filter hooks so
modules can implement and export new filters. Example filters are
an HTML filter (implemented), a profanity filter, an url converter,
ASCII smileys to images filter and so on ...
- Reworked the check_* functions: user contributed content/input is
only verified and filtered once in its lifespan.
NOTES
- Altough this is a large commit, no database changes are required.
