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

Next round of code review fixes are done. Some bigger refactoring has been done in another branch:

https://code.launchpad.net/~widelands-dev/widelands/refactoring-input-queue

Basically: "Using InputQueue instead of Wares-/WorkersQueue where it makes sense."

Also fixed/added some help texts and set the soldier quantity. What is left to do? I intend to add a builder-queue to expeditions in a further branch after this one has been merged.
