Refactor of prompts and the displayhook. * Renamed CachedOutput to displayhook.DisplayHook. * Added methods that DisplayHook.__call__ uses to do its work. These methods can now be overridden for the ZMQ kernel. * Removed all hooks (result_display and generate_output_prompt) that the outputcache was using. We need to add these back in once we figure out what to do about hooks in general.

Completed first pass of inputsplitter with IPython syntax. Code is now mostly ready for use. Upon review we'll probably restructure a few things, and there will likely be a few more classes created for extensibility. But for now, this is ready for the various frontends to start using.

Fix to ensure that the paging widget is styled appropriately.

* Restored functionality after major merge. * Refactored main() and lauch_kernel() methods for kernels.

Merge branch 'newkernel' of git://github.com/ellisonbg/ipython into qtfrontend Conflicts: IPython/zmq/pykernel.py

* Added a pager with several different options to ConsoleWidget. * Added a sensible size hint to ConsoleWidget.

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.

Add flushing to stdout/stderr in system calls.

Initial version of system command out/err forwarding.

Cleanup and minor UI fixes.
