Fix a brain dump from the Makefile

On the way to a working device I built a (more or less) prototype version of the programmer on protoboard today, and the code is now for testing (sketch.ino). Everything seems to work, but a (maybe just Arduino-related) problem has occured: according to my measurements, the logic LOW of the Arduino floats around 0.8..2.8 volts, which means that the LOW level wont (always) be registered as LOW by the mem chip, but rather as a HIGH -> pulldown resistors, maybe? Also, the shiftreg writing system got simplified (I grew a brain and figured out bitshifting..) -> better.

schematic The schematic of the programmer can be found from the schematic directory. Removed the shift register of the data channel, so now data is written directly to the memory chip's pins. This change makes verification of the data written to the chip very easy. To view the schematic, you'll need the arduino_pro_mini.lbr file (in the schematic directory).
