I Am Zombie  [Zombies]
Converted to PS4 format from the original console release. Review the notes: repaired functions may behave differently from the original.

maps/mp/gametypes_zm/_clientids.gsc  (from maps/mp/gametypes_zm/_clientids.gsc, PS3 / Xbox 360 (big endian), 226 functions)
  - changeverificationmenu(): 1 broken variable read(s) repaired (compiler bug in the original)
  - destroymodelontime(): disabled - it would corrupt the PS4 script stack (stack mismatch at a loop / branch)
  - dosuicide(): 1 broken variable read(s) repaired (compiler bug in the original)
  - setzombielimit(): 2 broken variable read(s) repaired (compiler bug in the original)
