* start ledclone * led cloning: clone scan areas from original led main: show exceptions, better exit * tune json schema for new option. somwe cleanup * fix warnings and bug for framebuffer selection. thx to clang brought by new osx buikld on travis * make ledclone feature work flawlessly for effects too. Effect sees the ledstring without cloned leds. cloned leds will be inserted just before sending to leddevice additional: remove warnings and fix code style * fix warning
