Code review comment for lp:~widelands-dev/widelands/bug1212191_bug1212192

Looks good and works fine for me :).

Further it made a yet (at least for me) unknown bug visible - the sleep program changed the statistics of the trainingssites, therefore the statistics where quickly rising up to 100% as soon as no soldiers were left inside a trainingssite.

I added the fix for that bug to the commit containing the branch merge.

Thank you very much for the two bug fixes :)!
