Music Player

So it would either be time consuming having to change each map or maybe a line of instruction could tell the Music Player to kick back to in its instructions. Either way it would have to be tested. Either that or I release the next update before Madsuir figures it out.

I think it's a bit time consuming but it's a fix. I'll try to set in memory somewhere the last valid map song and if when coming back from menu (and have started the music player) map song ID is 00, play that song. I haven't had time yet to look at the code but I'll try probably do Sunday, I got two mid-semester exams tomorrow so that was the priority.
