[Tinyos Core WG] Testing for 2.0.1

[Kevin Klues]

I've verified the following applications have README's and meet the
coding standards of TEP3:

RadioCountToLeds
RadioSenseToLeds
tests/TestAM
tests/TestArbiter

I've also made sure that tests/TestPrintf (as well as lib/printf in
general) works for telosb, mica2, and micaz, and that it has a README/
meets the coding standards for TEP3.  It should probably be included
now that lib/printf is part of the release.  You must be using
avr-libc1.4 or above in order for it to work on the mica motes,
however.  I've added this comment to the known limitations section of
the README.

We should also include the tests/TestSharedResource application.  It
is the test app referred to by tutorial 8.  I have made sure it meets
all the standards as well.
