Music issues

[Matriks404]

• [ ] Dumped music should loop correctly (create independent initialization track and looping one?)
• [ ] When paused, it should only play certain notes

By combining these two issues we can conclude that we need 4 tracks for every music piece:

• Initial track
• Initial track when paused
• Looping track
• Looping track when paused

Note that we should probably have 2 tracks (4 total) for different music notes, so in pause menu we can just turn volume down for one that doesn't play during that screen (love.audio.setVolume() function).

The problem with these are dumping them of course.
