- State code now properly calls action functions and has a RET instruction. As expected,

Browse source 
running with the checked VM can be quite slow, since it has asserts everywhere. Some other
  fixes were needed before the code actually worked:
  - A_CallSpecial needs to have its arguments cast to ints.
  - Some functions that set pnum/paramnum directly did not decrement it by 1. This also applies
    to A_Jump, though it just uses the value of paramnum instead of changing it.
  - Renamed pnum in the PARAM macros to paramnum, since pnum is already used in a few other
    places for something different, so this makes searching for it easier.
  This has not been tested especially thoroughly, but a first glance seems to indicate success.
