- Renamed "form.admin" to "form admin".

- Added node_admin_settings() to let users set node defaults.
    * Added _nodeapi("conf")
- Modified form_checkbox() to unset options. (Modified the patch from Ax.)
- Removed the _save() hook.
- Fixed a logical flaw in field_get() and field_set() which would break
  moderation.
- Moved some admin menus around and cleaned up some typos.
