New description:
This ticket removes the dependency of sage.misc.superseded upon
sage.rings.integer_ring.is_IntegerRing which was used for type
checking. This allows for using the functions in this module in code
that is imported early upon Sage startup, in particular in category
code.
By the way, this removes an unneeded test (the ticket number cannot be
None).
