* Add more legendary battle music; add music preference setting
* Replace BDSP tracks
"Souless", they say. Naysayers, I say.
* Update for settings menu refactor
* Remove unnecessary Reshiram/Zekrom music calls
The default legendary battle music is the Reshiram & Zekrom battle theme anyways, so removing these lines make it functionally identical.
* Update for settings menu refactor AGAIN
