MusicDefis used to store music themes config, and we need it for the whole lifetime of the application. However, the object was created byCMusicSys_Basson a stack and passed to theEngineas a reference. A moment later, the scope ofCMusicSys_Bassfunction finished andMusicDefwas deallocated despite being used by other classes.This change moves the ownership of
MusicDefto theEngine, so we can guarantee its lifetime.As a bonus feature, I added
HashStringthat can be used for compile-time string hashing (touint64_t) and as an efficient key for hash maps.
