Arduino testing

See here and here, and maybe here.

I have configured a job that verifies ScouseTom's Arduino code in src/arduino/ScouseTom_Control in Jenkins. See some related adventures in #8. The output of a successful run looks like this.
We should have a look at the links above and figure out what other testing is needed. Perhaps one Jenkins test per test in test/arduino?

Tests at Jenkins at the moment are only verifying the code, not doing proper testing yet since I assumed you couldn't test the code without ScouseTom actually plugged to the Jenkins node running the test. However, there's some information here that can help improve tests.
