#286913 by hunmonk: schema shows typo for unique index.  looks like the result is still correct in the database, so i don't think a db update is necessary.

Per-recent 6.x API change, make sure all child menu items have explicitly declared access definitions.

user_edit form renamed to user_profile_form. %user -> %user_category for menu item altering. fix notice.

capitalization fixes in help text. fix undefined var. use constant for anon user rid. fix submit handler in settings forms.

use db_placeholders() where appropriate. while the old code was not insecure, this approach is cleaner and safer in the long run.
