Forward button presses to FPGA in FPGA download mode (2) #43

Browse source 
This no longer has the delay as with the previous commit.
Bits are mapped to the following keys:
 0 - joystick down
 1 - joystick up
 2 - joystick left
 3 - joystick right
 4 - joystick press
 5 - home
 6 - menu
 7 - select
 8 - start
 9 - accept
10 - back
