Issue with invalid OOXML file

[Rafiot]

I have an XML file that I can open without any problem with LibreOffice but office dissector fails because the following parameter fails in the document:

<Default Extension="xml" ContentType="application/xml"/>

It seems the document should be considered invalid [1] but as it can be open with LibreOffice, I think office dissector should be able to handle it (the document is legitimate).

My dirty fix (?) right now is to default to self.__content_type = 'application/xml' if the parameter is missing.
