Buildbot configuration preliminary settings. Also added 'singletest.py' runner to perform test in one buildbot slave (non-thread safe)
LED test completion notification changed. Now if board do not have LED4, target will only blink LED1 to indicate test success. If test fails LED1 will not blink. This behaviour will be changed in the future. Now it is mainly removing compilation error (LED4 not defined).
