Use lex/yacc for parsing the config file. Re-work the config file 

format using a more human-readable format.

Read part descriptions from the config file now instead of hard-coding
them.

Update usage().

Cleanup unused code.

# c:<name>:[desc=<description>:][[<pin>=<value>:]...] # the programming hardware pinouts and also provides part definitions.
# AVRPROG's "-C" command line option specifies the location of the
# configuration file. The "-c" option names the programmer confiuration
# which must match one of the entry's "id" parameter. The "-p" option
# identifies which part AVRPROG is going to be programming and must match
# one of the parts' "id" parameter.
