arduino package release testing

[JohnD]

I did a few minor updates to the Arduino package to help with testing, so
can anyone with an Arduino UNO and some spare time try installing and
running it.

It required the Arduino IDE to be present, and the instrument control
package to be installed

The latest release dist is at:

https://sourceforge.net/p/octave/package-releases/_discuss/thread/64f6371d91
/eb87/attachment/arduino-0.4.0.tar.gz



Once installed, load the package and run the following to start the install
to the arduino uno that will be compatible with the test calls:

> arduino_bistsetup


The Arduino IDE should display. After pressing the upload button on IDE.
Close it (after the upload was done), it will perform a few verification
tests

Once completed, the normal bist testing can be performed using
__run_test_suite__
