[dev] Consider ignoring upload Content-Type

I would have no issue with this, as long as this is configurable.  And  
I believe that using the browser generated MIME type should remain the  
default, since it seems to work best most of the time (my personal  
experience is that the browser determination is *more* accurate than  
MIME magic determination).
