Music Player

I've updated the music player to version 1.3. The code saving the map song and resuming it after menu exit was already there but not fully working. I've fixed and improved it. Now the game save the song ID and volume when entering the main menu and resume both on menu exit. However the map song start from beginning.

This is a fix for map with song ID 00 as well as a fix for some volume problems. However I cannot disable / overwrite / replace what is in the entrance event after the menu exit meaning if you got anything there regarding song loading or fading, I'm not sure what will be the result. Logically, the menu song resuming should not have the time to kick in and entrance event song loading should have priority but it's a thing to test.

The custom functions also use menu RAM $D2-$D3 for song ID and volume saving.
