Many includes of fat.h are pointless. Some includes are just for
SECTOR_SIZE. Add a file 'firmware/include/fs_defines.h' for that
and to define tuneable values that were scattered amongst various
headers.
Remove some local definitions of SECTOR_SIZE since they have to be
in agreement with the rest of the fs code anyway.
(We'll see what's in fact pointless in a moment ;)

After placing the firmware.mi4 file in the root dir of the player in UMS mode of
the OF, Sansa should do stupid blinking with the backlight and buttonlight
alternately. Recovering from this state is possible through the recovery mode
(see Wiki), by putting an original copy of the firmware.mi4.
