Document options.score

[franklin-ross]

In the body of the Sifter.prototype.search function are the following lines:

// generate result scoring function
fn_score = options.score || self.getScoreFunction(search);

I take this to mean we can supply a custom score function, which is pretty neat, but undocumented on the project GitHub page. It would be better to have it documented.
