[BUG][PLAYER] Talismans and zombies

[Proxima]

When clicking on a talisman with a save requirement, the popup displays the requirement in the form "Save XX / YY" where YY is the total number of lemmings + neutrals + zombies on the level.

Zombies should not be included, because they are hostile entities and saving them isn't part of the goal.

Fixed in commit 49c1bbe. (To be backported to the 12.10 as well.)
