ObHack 008 crashes when given the attached parameters

[samboy]

When trying to make a level in ObHack 008, the game crashes when it tries to build a map.

Workaround: The map will build if key type is set to be "Skull Keys".

This bug is a regression introduced in commit 964ea16 (it worked before this commit, so I've create a 2015-07-13-works tag/release without this bug)

Workaround: Disabled the "old" game. While this doesn't fix the underlying bug (which is probably a simple case of there being no skull keys in the old game), it does make it possible to build games with card keys again. Closing (like the Hexen issue, I fixed the bug by disabling functionality).
