Changed the way that methods in pure mix-in classes are constructed. Methods and Acquisition wrappers use free list to improve allocation and deallocation performance.
Bound methods have attributes who's values are stored in their instances.
Acquired acquiring objects can nor acquire from the object they were accessed in, in addition to the object they were acquired from. Implicit or Acquisition. The acquire method available in earlier releases is still available, but is deprecated. Comparisons of objects with different classes didn't work correctly. Fixed comparison bug in Missing objects.
