[Cython] Cython 0.24 released

I'm happy to announce the release of Cython 0.24. Downloads can be found at http://cython.org/release/Cython-0.24.tar.gz http://cython.org/release/Cython-0.24.zip and of course on pypi. This release contains numerous features and bugfixes, most notably keeping up with several enhancements coming in Python 3.6 and deprecation of the old-style property syntax now that @property is fully supported. Some other significant changes are enumerated at https://github.com/cython/cython/blob/8b592122f23e0ce458521e5a828431c95a0d84... Thanks to all those who contributed code, ideas, and testing! - Robert
