// The base class for sector actions ----------------------------------------
- disabled the scripted virtual function module after finding out that it only works if each single class that may serve as a parent for scripting is explicitly declared. Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going. It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

- fixed several Destroy methods which blanketly assumed that the object's pointers were valid to use without checks. This is not the case if deserialization prematurely aborts. The entire object may be invalid if something in the deserializer I_Error's out.

- removed the sequential processing of JSON objects because the benefit is too small. After testing with a savegame on ZDCMP2 which is probably the largest map in existence, timing both methods resulted in a speed difference of less than 40 ms (70 vs 110 ms for reading all sectory, linedefs, sidedefs and objects). This compares to an overall restoration time, including reloading the level, precaching all textures and setting everything up, of approx. 1.2 s, meaning an increase of 3% of the entire reloading time. That's simply not worth all the negative side effects that may happen with a method that highly depends on proper code construction. On the other hand, using random access means that a savegame version change is only needed now when the semantics of a field change, but not if some get added or deleted. - do not I_Error out in the serializer unless caused by a programming error. It is better to let the serializer finish, collect all the errors and I_Error out when the game is known to be in a stable enough state to allow unwinding.
