Changing how IPython.utils.io.Term is handled....

Changing how IPython.utils.io.Term is handled. We used to create a module level IOTerm instance called IPython.utils.io.Term when IPython.utils.io was imported. We now delay this until InteractiveShell.init_io is called. This gives us a chance to override sys.stdout/sys.stderr first. All code that uses IPython.utils.io.Term must refer to by its full name: "IPython.utils.io.Term" and not hold references to it.
