Make the pin definitions configurable based on entries in a config

file.  This makes supporting other programmers much easier.

Rename AVRprog.pdf to avrprog.pdf.

+Use the specified config file to locate the desired pin configuration.
+Pin configurations are specified in the config file using a colon

+.Ar PIN
+can be

+The value is the pin number of the PC parallel port assigned to that
