Bug#935849: tutorial: wrong bin link

[darkdragon]

Also, the tutorial should include "jarwrapper" in the example
"debian/control" so that copy&paste just works. The section about
"jarwrapper" in the tutorial gives further explanation in case anyone
is interested.

Maybe a hint about overwriting targets in "debian/rules" should be
given as well:

override_jh_build:
    jh_build --main ClassName

Probably it would be best to add a new section to the tutorial
summarizing all these findings!
