title: py2exe PackageNotFoundError
body: <p>I'm currently trying to package a Tkinter app into a .exe file using py2exe. The packaging works fine, and up until a point, the program functions. When I call a certain function, though, running the .exe file logs the following error:</p>
  
  <pre><code>Exception in Tkinter callback
  Traceback (most recent call last):
    File "Tkinter.pyc", line 1532, in __call__
    File "/Users/Gordon/Gordon's Files/AutoFormatter/lib\formatterApp.py", line 58, in go
    File "formatter.pyc", line 72, in take
    File "docx\api.pyc", line 25, in Document
    File "docx\opc\package.pyc", line 116, in open
    File "docx\opc\pkgreader.pyc", line 32, in from_file

  PackageNotFoundError: Package not found at 'C:\Users\Gordon\Gordon's Files\AutoFormatter\dist\library.zip\docx\templates\default.docx'
  </code></pre>
  
  <p>Upon originally running py2exe, I checked the \docx\ folder and found that py2exe hadn't actually copied over the \templates\ folder. After manually unzipping the library.zip, adding in the \templates\ folder in the right place, and then manually re-zipping, however, I get the same error. </p>
  
  <p>My setup.py is as follows:</p>
  
  <pre><code>from distutils.core import setup
  import py2exe
  
  setup(
      windows=[{'script': 'AutoFormatter.py'}],
      options={
          'py2exe': 
          {
              'includes': ['lxml.etree', 'lxml._elementpath', 'gzip', 'docx'],
          }
      }
  )
  </code></pre>
  
  <p>I'm running the program on a Windows 7 computer using Python 2.7.8 and py2exe 0.6.9.</p>
