Map .pyx sources to .c or .cpp depending on language
Merged in lsinger/setuptools (pull request #39)

Map .pyx sources to .c or .cpp depending on language
Use a single method to handle both languages.
self.language could be None (and is None by default)
Use functools.partial and re.sub to construct the substitution function.
Issue #162: Update dependency on certifi to 1.0.1.
Reindent and remove excess whitespace
Remove special handling of 'no_compile' option with comment about making DISTUTILS_DEBUG work right. While testing on Python 2.6 and later, I was unable to evoke any abberant or distinct behavior by removing the value (with DISTUTILS_DEBUG enabled and using variations of --compile and --no-compile). Therefore, I believe that whatever was the motivation for adding the attribute (in 2c91c12dc9b1), its purpose has passed.
