store level turn for each level
fix the nlp and freebie
last version is not working since I change the getLevel() function and $level seems to be related to nlp, so keep all the original code, add another function to get level counts and hope this time will  work
STUPIDROBOT another change for freebie
the original one didn't get the right level in the $level->level
