auto_props and setting the same property multiple times?

I checked the manual and came to the same conclusion. I have change the 
auto_props code to first set the mime-type based on the binary flag and 
then check for auto properties. So if the mime-type is overwritten by 
the auto_props, we will loose application/octer-stream in favor of a 
better description.

Since I don't have much experiences with properties, I was wondering, 
whether it is possible to have multiple mime-types. E.g. I dealing a lot 
with PDF files but i'm interested in rendered images of the PDF file. So 
I would assign a "image/PDF" mime-type instead of "application/PDF". But 
both views of it a correct, so having both wouldn't be totally wrong.
