- added a stripped down version of ZDoom's DObject.

This only retains the objecct factory feature, but removes the garbage collector which I have no use for.

** The particular scheme used here was chosen because it's small.
**
** An alternative that will work with any C++ compiler is to use static
** classes to build these lists at run time. Under Visual C++, doing things
** that way can require a lot of extra space, which is why I'm doing things
** this way.
**
** In the case of PClass lists (section creg), I orginally used the
** constructor to do just that, and the code for that still exists if you
** compile with something other than Visual C++ or GCC.
