[issue21652] Python 2.7.7 regression in mimetypes module on Windows

[James Y Knight]

New submission from James Y Knight:

The change done for issue9291 in Python 2.7.7 caused the mimetypes.types_map dict to change to contain a mixture of str and unicode objects, rather than just str, as it always had before.

This causes twisted.web to crash when serving static files on Windows. See https://twistedmatrix.com/trac/ticket/7461 for the bug report against Twisted.
