- instead add a list of SpecialInits to VMScriptFunction so this can be done transparently when setting up and popping the stack frame. The only drawback is that this requires permanent allocation of stack objects for the entire lifetime of a function but this is a relatively small tradeoff for significantly reduced maintenance work throughout. - removed most #include "vm.h", because nearly all files already pull this in through dobject.h.

** Much of this file is fudging code to compensate for the fact that most of
|
|
** what could be changed with Dehacked is no longer in the same state it was
|
|
** in as of Doom 1.9. There is a lump in zdoom.wad (DEHSUPP) that stores most
|
|
** of the lookup tables used so that they need not be loaded all the time.
|
|
** Also, their total size is less in the lump than when they were part of the
|
|
** executable, so it saves space on disk as well as in memory.
