algorithms.c: Support the new 16-bit key-size descriptors.
group.c: Track Catacomb group internals change.
utils.c: Raise exceptions from `convTHING' with null arguments.
Return `long' objects when `int' is requested but the value won't fit.

debian/control (already wanted later catacomb-dev)
group.c (no need for compatibility with older Catacombs)
