Travis had some trasient Issue only
> ... could not connect to ppa.launchpad.net:80 (91.189.95.83), connection timed out
> Unable to locate package g++-6

Same for appveyor:

Code changes look straight forward, will compile and testplay this now.

[kaputtnik (franku)]

Tested with the fh1-tutorial2 branch and all LGTM :-)

review: Approve (testing)

[Klaus Halfmann (klaus-halfmann)]

Test this with
./wideland --scenario=/<AbsolutePathTo>widelands-repo/fh1-tutorial4/data/campaigns/tutorial04_economy.wmf/

kaputtnik: Did you test in English or in German?
I will then test the other variant.

[kaputtnik (franku)]

Oops, didn't test the objectives and there was one issue. In the 'Open the Ware Stastics window' part was a useless paragraphdivider(). I removed it and all looks good now.

[kaputtnik (franku)]

I have tested in english. The language shouldn't matter, as long the language has no special cases, imho.

Continuous integration builds have changed state:

[kaputtnik (franku)]

Klaus, did you finished your test?

[Klaus Halfmann (klaus-halfmann)]

Yes finished in German and found a few missing translations only.
In trunk I found, that the help for bulding sites is some HTML only.

review: Approve (compile testplay)

[kaputtnik (franku)]

> In trunk I found, that the help for bulding sites is some HTML only.

This is another task, imho

Thanks for testing :-)

Refusing to merge, since Travis is not green. Use @bunnybot merge force for merging anyways.
