WestfW 07dfd77554 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.

Optiboot does not support ArduinoasISP programmer.

When avrdude runs and talks to an arduino running ArduinoISP,
it needs the optiboot (entered due to auto-reset) to abort and
start the ArduinoISP "application" when it sees communications
at the wrong serial speed.  Unfortunately, optiboot treats all
unrecognized command characters as "no-ops" and responds/loops
for more commands, leading to a nice loop that never gets to
the sketch.   This patch causes characters received with Framing
errors (the most likely error for speed mis-matches) to NOT
reset the watchdog timer (normally done in getch()), which will
cause the application to start if it continues for "a while."
(tested.  Works!  Running ArduinoISP at speeds as high as 57600
still causes the bootloader to start the sketch (although it fails
later on for other reasons.))

WestfW 6f7731bb6d Makefile modification to allow building optiboot in more environments.
Allows building within the Arduino Source tree, and within the Arduino
IDE tree, as well as using CrossPack on Mac.

Adds README.TXT to track arduino-specific changes (and documents the
new build options.)

This addresses Arduino issue:

  http://code.google.com/p/arduino/issues/detail?id=487

And optiboot issue

  http://code.google.com/p/optiboot/issues/detail?id=1

(which can be thought of as a subset of the Arduno issue.)

Note that the binaries produced after these Makefile changes (using any
of the compile environments) are identical to those produced by the
crosspack-20100115 environment on a Mac.
