Give higher weight to freeleech torrents

Freeleech was previously ignored, and caused a golden torrent to get priority over the freeleech.

I set the score to +7000 for freeleech (vs +5000 for golden) -- I'm not sure what is best since it is not particularly clear which one would win in a tie breaker. Perhaps it would be better to change these options to "Bonus for Freeleech", and allow the user to enter a number? Since it is already enabled by default, we could just default to the current values.

Also, as a side note: I am not explicitly checking what the Value of FreeleechType is since it only shows up if the torrent is marked freeleech. I am not sure what the syntax of things like halfleech and neutral leech is (none available at the moment).
