ContextualZipFile tried to be smart and have its __new__ method return
zipfile.ZipFile instances on Python versions supporting the zipfile.ZipFile
context manager interface (i.e. only on Python [2.7, 3.0> & 3.2+) while on
others it would return an actual ContextualZipFile instance.

The new implementation seems much simpler and avoids a DeprecationWarning on
Python [3.0, 3.2>. There zipFile.ZipFile's __new__ method implementation is
actually inherited from object, and calling object.__new__ with extra
parameters has been deprecated since Python 2.6 (it has even been converted to
an error since Python 3.3).

Notes on why there were no related problems in other Python versions:
* Python versions prior to 2.5 were not affected because they did not yet
deprecate passing extra parameters to object.__new__.
* Python version 2.6 was not affected because there zipfile.ZipFile was
implemented as an old-style class and therefore did not get its __new__ method
called in the first place.
* Python [2.7, 3.0> & 3.2+ - explained above.

Include the build launcher script in setuptools sdist. This helps address the requirement that all sources be included.

Patch globals in a function. This technique bypasses the linter warnings about the names not being present, and allows for better documentation.

Use StringIO to write out requirements. Use more common convention of adding newline to each line of the file, not just intervening lines.

est_manifest_is_written_with_utf8_encoding should use the filelist's append, NOT filelist.files.append

Convert quiet to a context manager, so its comment is no longer complaining and to simplify the code.
