Code review comment for lp:~flegu/widelands/fix_some_memory_leaks

Code LGTM :)

You now need to add some headers to make Codecheck happy, then this can go in.

widelands/src/ui_fsmenu/loadgame.cc:117: This file uses unique_ptr but does not include <memory>.

widelands/src/wui/load_or_save_game.cc:171: This file uses unique_ptr but does not include <memory>.

widelands/src/wui/load_or_save_game.h:46: This file uses unique_ptr but does not include <memory>.

The reason for this rule is that some compilers will barf if unique_ptr is used without this header.
