* main.c: revert to rev 1159 (doing pgm_display after pgm_open) 

* avrpart.[ch]: moved avr_pin_name to pindefs.[ch]
* pgm.c: moved pins_to_str to pindefs.[ch], added initialization of 
          new pin definitions in pgm_new()
* pindefs.[ch]: added moved functions from other files, added a lot of 
          documentation, reformatted files using astyle to have consistent spacing,
          added a new generic check function for pins
* ft245r.c: used new generic pin check function
