more download direct links

I'm still working on the direct download issue with files served by google drive. Firstly, my test file was empty or corrupted so that muddled my trouble shooting. I can indeed download documents from the direct download link. However, I still can't see the file name and extension, nor can I easily read the content disposition of the url with python's urllib tools. I still may need to find a way to parse the data "blob" in order to read the type of file before i let weblogo download it.
