Adds a lot of stuff

- new commands
SetLevel (level) - Set all characters' level (between 1 and 999 takes effect on game and server restart)

SetSkillLevel (level) - Set all characters' skill levels between 1 and 10 (takes effect on game and server restart)

addallcharacters - Add all missing characters to the selected user with default levels and skills (takes effect on game and server restart)

- partial gacha support works
only 10x adds bodies (they still cant be used and it includes normally inaccesible characters like marian)

-partial jukebox support allows for listening but not setting lobby / commanders room bgm unless manually changed in db.json
