*Reworked almost everything about alternate DOL loading (I am wondering how loading from SD/USB even worked) *Added new Option "Default" for alternate DOL which is now the default settings. This setting will select the alternate DOL automatically for games like Red Steel 1 because this alt. DOL is always needed to play the game. On games where the alt dol option is not needed the option "Default" = "OFF". This is just an attempt to make this option more automatic. Games like Metroid Prime (the only game right now) will have a prompt on game start where you choose between 1, 2 or 3 on this option because this game always requires either of these. *Small source cleanups/fixes
