IPython/Extensions/ipipe.py: xrepr(), xiter() and xattrs() are now...

IPython/Extensions/ipipe.py: xrepr(), xiter() and xattrs() are now generic functions (using Philip J. Eby's simplegeneric package). This makes it possible to customize the display of third-party classes without having to monkeypatch them. xiter() no longer supports a mode argument and the XMode class has been removed. The same functionality can be implemented via IterAttributeDescriptor and IterMethodDescriptor. One consequence of the switch to generic functions is that xrepr() and xattrs() implementation must define the default value for the mode argument themselves and xattrs() implementations must return real descriptors. IPython/external: This new subpackage will contain all third-party packages that are bundled with IPython. (The first one is simplegeneric). IPython/Extensions/ipipe.py (ifile/ils): Readd output of the parent directory which as been dropped in r1703. IPython/Extensions/ipipe.py (iless): Fixed. IPython/Extensions/ibrowse: Fixed sorting under Python 2.3. More docstrings. Moved xrepr(), xiter() and xattrs() documentation into the docstring of the default implementation.
