(hopefully) fixed save data loss bug

soundtrack menu:
-set player init function to set music volume to users music volume setting (hopefully stop volume being 'reset' to 100% on run restart)

-fixed check for fading in music over the run start intro jingle not triggering unless the user was running repentogon

-added option for changing the jingle setting of all soundtracks, so you don't have to set each one individually if you have a large number of them

soundtrack menu:
