Fixed the Utero theme slowly fading out in hostile rooms due to a mistake with how Repentance does layers.

It has been scientifically proven that I cannot type.

Bugfix for previous update.

Fixed boss themes not playing due to accidental usage of an undefined local.

Slightly changed the Ashpit and Dross tracks.

- Fixed the boss over jingle for the Alt path being too loud
- Fixed secret room and treasure room jingles interrupting floor music
- Received several reports about various boss tracks not working, couldn't reproduce these.

Now fully compatible with the music mod callback, with no bugs as far as I can find!

Also added boss outros, fixed a few layering problems and rewrote the entire lua script to make more sense.

After playing with the music mod callback enabled, it has come to light that there are a couple very annoying bugs.

I am removing compatibility with MMC until I'm fairly certain I've ironed out all the problems, then I'll update the mod again.

Don't know why I thought steam would automatically ignore the .git folder... It's removed now, cutting the download size in half.

Now supports Music Mod Callback for better performance! Also fixed some issues with the Void music randomizing.
