Subject: * Moving all of the prioritization/reprioritization code into a new
 file Prioritizer.cs * Simplified the interest management code to make it
 easier to add new policies. Prioritization and reprioritization share code
 paths now * Improved the distance and front back policies to always give your
 avatar the highest priority
