Hello, so far the multiboot support is not included in the documentation. This small patch changes docs/Runtime_config.md to include multiboot. I think adding how to use multiboot with Grub would be nice, but this does not seem to fit to the content of Runtime_config.md. Do you have any suggestions where to put it?

This example shows how to start SeaBIOS from Grub2 via multiboot. SeaVGABIOS is passed as a module. ``` set root=(usb0,msdos1) multiboot /bios.elf.bin module /vgabios.bin name=vgaroms/seavgabios.bin boot ```
