Why? So mods that reveal enemy names don't show internal monster class names.
Tags are based on language.enu lump:
- Tags for Doom/Doom 2 monsters are referring directly to CC_* strings.
- Tags for Heretic monsters are based on obituaries.

This function calculated everything correctly but ultimately set the vertical velocity wrong. Most importantly this meant that the actual velocity vector and actor pitch - if CMF_SAVEPITCH was used - did not match.
Since this bug has been present since the pitch parameter was added, this deprecates A_CustomMissile and replaces it with a properly implemented A_SpawnProjectile function and handling the compatibility case with a new flag and a scripted wrapper function.
All internal uses of A_CustomMissile have been replaced as well.
