Merge lp:~nomeata/widelands/726139 into lp:widelands

[Joachim Breitner]

I have pushed a branch that implements updating of WaresDisplay (e.g. in a warehouse) using a boost::signal. The code is very straight forward; the effect though is very nice and slick – when a worker enters the building it updates so fast that I don’t even see the number changing.
