Add a script to compile examples as an automated test suite.

* Added script/boostrap.sh to download the Arduino IDE and MPIDE (for
    chipKIT). Tested in Linux, should work in Cygwin and OS X too.
* Added script/runtests.sh to run "make" in each example project and
    collect the results. The script returns -1 if any fails.
* Moved currently testable examples to a "tests" directory, separate
    from examples that require alternative cores.

+/* Blink without Delay
+ 
+ Turns on and off a light emitting diode(LED) connected to a digital  
+ pin, without using the delay() function.  This means that other code
+ can run at the same time without being interrupted by the LED code.
+ 
+ The circuit:
+ * LED attached from pin 13 to ground.
+ * Note: on most Arduinos, there is already an LED on the board
+ that's attached to pin 13, so no hardware is needed for this example.
