Add minunit test framework (#168)

* add minunit tests

* fix logging

* ignore unexisting time service on embedded targets

* fix warning, issue with printf

* add exitcode

* migrate to printf

* indicate test by leds

* add testing description

* redesigned minunit tests to allow testing in separate files

* add test step for local target

* add failure test

* add restore test_check

* testing description
