Retire the unused per-node permission subsystem

Every path through Permission raised or lied: validates_presence_of on a
boolean made granted = false unsaveable, since false.blank? is true;
get_permission_for read a nonexistent identifier attribute; has_permission?
called an undefined plural method and returned a truthy relation in every
case; and set_permission mutated granted without saving. Nothing outside the
model referenced it and the table was empty.
