Add Angus Gratton's port to Teensy++

On 2010/06/28, from Angus Gratton on the maillist:

2) teensy_support.patch <-- Teensy++ support

Teensy++ is a USB development board (http://pjrc.com/teensy/). It's
built around a AT90USBxxx micro (8kb RAM, 64 or 128kb flash.)

The main difference to the other AVRs is it has no USART, so emulates
serial using the built-in USB support. For that reason I put it into its
own platform/ directory, although it could also be implemented as part
of platform/avr/ by using lots of #ifdefs.

For a demo app, platform/teensy/main.py is a reimplementation of a
Teensy demo program called "blink" that blinks Morse code on the
built-in LED while outputting the same strings to the serial port.
Unfortunately, this simple program, written in pure Python without much
consideration for embedded tricks and techniques, takes up nearly all
the RAM on the Teensy++!!

r571
- Applied patch
- Renamed calls to sleepMs to delay (see Issue #126)
- Added notes to the README about selecting Teensy++ hardware version 1.0 or 2.0

I don't have a device to test this.  Compiles without error.
Mainlined directly.
