Merge lp:~widelands-dev/widelands/bug-1721121-workers-invisible-wares into lp:widelands

[GunChleoc]

Restored ware hotspot and animation to workers. Made some variables in WorkerDescr private and/or const.

[bunnybot (widelandsofficial)]

Continuous integration builds have changed state:

Travis build 3376. State: passed. Details: https://travis-ci.org/widelands/widelands/builds/366705865.
Appveyor build 3182. State: success. Details: https://ci.appveyor.com/project/widelands-dev/widelands/build/_widelands_dev_widelands_bug_1721121_workers_invisible_wares-3182.

[Notabilis (notabilis27)]

If I am not mistaken, this mostly just moves code around, right?
The lost wares are back and the code is looking good so in my opinion this can go in.
If you want to: two small nits regarding the documentation.

review: Approve (diff, testing)

[GunChleoc (gunchleoc)]

Thanks for the review - fixes applied :)
