Add 'make fuses' capability to Makefile #91

... in such a way that AVRDUDE -B10 is used to ensure slow write speed and 
write all three fuse settings in one call.

Done.

Used -B8 == 8uS clock period -- or 125KHz -- for safety, this is half the 
maximum rate of 250KHz for a factory new ATmega2560/1, running on its internal 
1MHz clock.

NOTE: It is unknown how faithful any particular, physical programmer device 
will be for the -B8 (125KHz) setting. I have tested it (roughly) with an Atmel 
AVR ISP mkII, where it seemed to perform correctly and believe it should work 
OK with USBasb devices, based on the firmware source code I've see.
