Pprintpp

* Add IPython plugin (thanks roee30;
https://github.com/wolever/pprintpp/pull/20)

* Add support for subclasses of built-in collections and collections
module (ex, if no __repr__ is defined, a subclass of dict will be
repr'd ``MyDictSubclass({...})``).
* Add support for ``collections.OrderedDict``
* Add ``quiet=True`` flag to monkeypatch
* Fixed crash on non-hashable instancemethods
(https://github.com/wolever/pprintpp/issues/18)

* Oops, fixed setup.py so the module is actually push'd to PyPI (thanks
OldhamMade).
* pprintpp is now a package, not a single .py file.

* Add Python 2.6 compatibility (pprintpp will work without the
`collections` module; thanks ulope)
* Fix set/frozenset bug on PyPy
* Fix sorting of heterogeneous containers on Py3

* Some minor bugfixes

* Add Python 3 support
