Improve DFU procedure :

 - correctly write all bytes to flash
 - check CRC
 - Fix bug in notification : they cannot be sent from the control point handler (because it seems you cannot send a notification and a write acknowledge at the same time) using a timer (quick'n'dirty implementation to be improved)
 - Improve dfu screen
 - Reset if dfu image is correctly copied into flash and crc is ok.
