Fixed #23. QtD_QObjectEntity is not created dynamically for shell classes any more. Class initialization is now performed by static constructors. When wrapping QObjects returned from functions, their run-time types are now taken into account. QObjects are allocated on GC heap, a doubly-linked list is used to prevent them from been collected (arguably a better solution than allocating on C heap and adding GC ranges) Minor changes (including unnecessary).
