Add support for fetch options

[dsl101]

I needed to be able to pass options to the underlying fetch to adjust timeout, etc. Here's a patch to enable that, in case it's of use to anyone else:

Hi - sorry, I don't have time to go through the hoops now I'm afraid, as I decided to take a different approach (which doesn't use feed-reader). But those 2 lines above are all that's needed I think.

@dsl101 ok, thanks. I will try doing it by myself.
