[Cython] Cython 0.9.6.14 released

[Robert Bradshaw]

Cython 0.9.6.14 is out. This is mostly a bugfix release, however  
there are several other improvements, notably:

- Source code encoding support (PEP 263) and UTF-8 default source  
encoding (PEP 3120) (Stefan Behnel)
- New command line option -w to change the working directory when  
running Cython (Gary Furnish)
- L.append(x) now optimized if L a (runtime) list (Robert Bradshaw)
- Cdef variables may be declared python builtin types (CEP 507),  
though there is much more potential for optimization (Robert Bradshaw)
- Enums declared "public" will get exported to the (python- 
accessible) module namespace (Robert Bradshaw)
- Correct special float values (Christian Heimes/Stefan Behnel)

Thanks also to all those who submitted good bug reports as well.
