Allow the READ PARAMETER command to return our version number.
(significant size impact: 14 bytes!)
Initialized "address" to eliminate compiler warning (4 bytes!)
Add "atmega168" as a more accurate target name than "diecimila"
(keep diecimila as well for backward compatibility)
Reduce the .hex and .lst targets that are stored in source control
to the three basics: atmega8, atmega168, atmega328. The other
targets remain in the makefile and makeall, but will need to be
built from source if wanted. Which should be less of a problem
now that the source is buildable without installing crosspack.

The "atmega8_isp" target does not currently work, because the mega8

doesn't have the "extended" fuse that the generic ISP target wants to

pass on to avrdude. You'll need to run avrdude manually.

I've reduced the pre-built and source-version-controlled targets

(.hex and .lst files included in the git repository) to just the

|
three basic 16MHz targets: atmega8, atmega16, atmega328.
