* FIFO on arm7 appears to now work as intended.
* GBA mode switch funcition remains broken.
* Default GBA_Exploader.ini file now created if one is not present.
* Moved GBA_File struct to ctrl_tble and removed duplicate from main.c.
This was causing issues where I would forget to update both when I
removed the now unused Alias char array. All code now shares the single
instance which will prevent this issue should this struct need to be
updated in the future.
* UI appears to function correclty. As I do not have a compatilbe slot-2
device I can't test further.
* Soft reset into GBA mode not yet fixed so likely not working yet.
* File browser untested. Ported fixes from NDS_Backup_Tool but untested
due to lacking compatible slot-2 hardware.
