Unittests via embUnit

[miri64]

Add Unittest framework embUnit and start writing tests.

Edit: Completely replaced minUnit with embUnit, as discussed in meeting ⇒ deleted obsolete comments

No longer WIP, please review. Actual tests for core moved to #961

[OlegHahm]

readme.txt looks corrupted.

[OlegHahm]

For consistency I would prefer Makefile to be spelled with a capital M.

[OlegHahm]

Is there anything that can be actually reviewed in this PR?

Am I missing something?

[miri64]

@OlegHahm miniscule Makefiles are from embunit. Please refer to #961 (or https://github.com/RIOT-OS/RIOT/wiki/Testing-RIOT) for building.

[OlegHahm]

I did and it says I should run

cd tests/unittests
make

[miri64]

Above you were in tests/unittests/embunit according to your paste. Anyway, you need #961 to build something.

[OlegHahm]

Ah, sorry, my bad.

[miri64]

Rebased and squashed.

[OlegHahm]

Looks good as far as I can tell. ACK

[miri64]

So can I merge it?
