Added tests 0.1 and 0.2 (XMPP Server)

We now have both as well as test 2.1 (yet I'm querying for a SRV record
instead of a TXT record).

I need to change the test framework so that it issues tests in order,
following a certain dependency chain.

I want to do it in way that someone can easily issue an specific test
again without having to run all previous tests again, but I think I will
need some state in order to do so.

I guess I won't have a stateless test API anymore.
