This doesn't work, the tags <PerkTreePosX> and <PerkTreePosY> are missing so the skills are unselectable. Adding them in and fixing a little formatting due to comments make it work fine, though. I put the essence skills in 3,2 4,2 and 5,2, slave driver at 0,4 and bookwork at 2,4 (those are all empty on the base governer skill tree)
