Add patch function to cure side effects of bug just fixed.
Add patch function to cure side effects of bug just fixed.

To fix:

1  For each object:
1a.   Save the value of "archetypes"
1b.   Call thing_wipe_archetype
2.  For each object, set_archetypes() with the saved values from 1a.

Suspending the mud during this patching operation is advised.  At the very
least, calls involving changing archetypes must be suppressed until all
objects are patched.
