Prevent BlobItemContainer from receiving focus.

This seems to fix https://code.google.com/p/camlistore/issues/detail?id=183.
I could not find the code that is actually causing scrolling to occur ... I am
guessing something in Closure somewhere.

However, I also couldn't think of any reason for this component to be
focusable, and this doesn't seem to break anything that I can see.
