Instead of replicating the RGSS Disposable interface in C++ and merely binding it, redefine the 'disposed' state as the entire core object being deleted (and the binding object's private pointer being null). This makes the behavior more accurate in regard to RMXP. It is now for example possible to subclass disposable classes and access their 'dispose'/'disposed?' methods without initializing the base class first (because the internal pointer is simply null before initialization). Accessing any other base methods will still raise an exception. There are some quirks and irregular behavior in RMXP; eg. most nullable bitmap attributes of disposable classes (Sprite, Plane etc.) can still be queried afterwards, but some cannot (Tilemap#tileset), and disposing certain attributes crashes RMXP entirely (Tilemap#autotiles[n]). mkxp tries to behave as close possible, but will be more lenient some circumstances. To the core, disposed bitmap attributes will look identically to null, which slightly diverges from RMXP (where they're treated as still existing, but aren't drawn). The Disposable interface has been retained containing a single signal, for the binding to inform core when objects are disposed (so active attributes can be set to null).
