mime email creation with attachment

[Jason Trowbridge]

You forgot a header to make it a valid MIME message.  I added a line to
the segment of code below:

> def mailFileToUser(_userName, _fileName):
>        outputfp = StringIO.StringIO()
>        w = MimeWriter.MimeWriter(outputfp)
>        w.addheader("subject", "Strip studie rapport")
--->     w.addheader("Mime-Version", "1.0")
>        w.flushheaders()
