Fix mob spawner crash (#4337)
This fixes #4336 crash at login about mcl_mobspawners. Also adds an API call, `mcl_mobs.register_conversion` for converting one mob into another and updates rovers and stalkers to use this API call.

Registering Mob Conversion
|

----------------
|

|

Sometimes you need to completely replace one mob with a different version. To do this, use:
|
||||
|
||||
mcl_mobs.register_conversion(old_name, new_name)
