Subject: JSUList.h templates and JKRHeap matches (#13)

* JSULink, JSUList, JSUTree and more matching in JKRHeap

* Added JSUListIterator and decompiled JKRHeap::dispose_subroutine

* more templates and JKRHeap functions

* JKRDisposer!

* only 4 functions not OK in JKRHeap

* fixed: *this->getObject()
