* 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.
