Subject: Disable bootloader messages in the H10 and Sansa bootloaders unless
 the PLAY (on H10) or RIGHT (on Sansa) button is being held.  Messages are
 still displayed if an error occurs.  This has already been implemented for
 iPod bootloaders, but still needs implementing for the other bootloaders.
