Code review comment for lp:~widelands-dev/widelands/empire04_unused_key_return_on_dismantle

Indentations will be fixed by bunnybot. I have set my IDE back to tabs from spaces, so it will be a bit less crazy in the future.

The dismantle tooltip now only says "Dismantle" when there are no wares returned. I have tried out some alternatives and I think that looks best.
