I decided to go hog wild and clean up all the type use in Presents which

required some serious bending and folding of the generic type system, but for
the most part we managed to avoid any mutilating. The gendobj task now
generates properly typed "addToXXX" and "updateXXX" DSet methods based on the
parameterized type of the DSet. This might cause unrecompiled code to break,
but I don't think there are many cases in the base toolkit where people call
DSet adders or updaters. We'll see and I'll add backwards compatibility
versions for cases where we need them to support GG games (everything else we
can just recompile).
