Simple option page to select the match algorithm

Hi Ian,

I included a very simplistic option page to allow setting the algorithm to be used to calculate matches. It makes use of the html 5 localStorage API. Let me know what you think.

with kind regards,

The option page itself looks like crap, but I would like to get the underlying logic nice and proper before working on the esthetics. In addition I don't really have a lot of experience with html/css so I would welcome any help on that front ;-)
