Added 2 more options to blue screen: c) BOOT_DEBUG_PRINT and d) BOOT_LAUNCHER_START. Existing option "Boot device" is now e).

Browse Source 
BOOT_DEBUG_PRINT = If set to "yes"/"on", will duplicate debug output to the screen. Default is "no"/"off".
BOOT_LAUNCHER_START = If set to "no"/"off", LAUNCHER application won't be run after kernel has loaded. Default is "yes"/"on".
