This release adds the oo module, which implements object-orientation. It also reworks the module system's ::, so as to be an immediate word that takes a module off the stack, and export, so the word to be exported can be any xt taken off the stack. Finally, it adds qagain, which is like a begin ... again loop but takes an xt which it executes in a loop forever (until an exception is raised or the task is killed).
