Kari Salminen add07fceaa Added loading of temporary Operation Stealth savegames. Needs testing!
- Music related settings and adBgVar0 & adBgVar1 aren't loaded currently.
Modified resetEngine to also reset more of the Operation Stealth specific variables.
Added getter for background scrolling value.
Changed additional background indices 1 & 2 from byte to uint16.
Made savegame loading functions return !in.ioFailed() as return value instead of true as previously.
