build-system: import build system from HelloSTK2

The current build system (Makefile) uses a very old java SDK that is no
longer available on modern platforms.

There is a community supported project HelloSTK2 (maintained
by Merlin Chlosta, see also [1]) that uses not only a comfortable ANT
based approach. It also uses more modern Java SDKs which are automatically
downloaded using .gitmodules. All this makes it very comfortable to use
and also lowers the barrier for beginners.

Let's take this approach as an example and use it in our hello-stk.git
as well.
