Merged in the core branch. This is a major update that fixes many things, and
changes many others, including source files that were deleted and renamed. Before doing this update, I reccomend a full clean, or even a fresh checkout. Things to note, most outstanding about this update: - Bu::Socket was changed to Bu::TcpSocket and the default mode is blocking. - All templatized container classes are SharedCore now, which is good, but SharedCore is inherently non-reentrant safe. However, all SharedCore classes have a "clone" function that return a non-shared copy of the object, safe for passing into a reentrant safe function accessing shared memory.
