Title: get rid of trackable_classes array (attempt 2)

Not sure if other people find this (would be very interesting to know), but at least for us this code causes our rails process to grow in memory as classes are reloaded (e.g. in development mode). Given ```trackable_classes``` doesn't seem to be used anywhere, maybe simpler just to remove it?
